Ithiyori ye-PID yoMlawuli we-Servo oqhubekayo: Qonda ithiyori ye-PID yolawulo olululo lwe-servo.
Imveliso yesiphaluka solawulo lwe-PID, u(t), inikwe njenge

Apho:

• ?? yinzuzo elinganayo, engenamda
• ?? yinzuzo edityanisiweyo kwi-1/sesekhondi
• ?? yinzuzo ephuma kwimizuzwana
• ?(?) luphawu lwemposiso kwiivolthi
• ?(?) sisiphumo solawulo kwiivolthi

Ukusuka apha sinokuchaza iiyunithi zolawulo ngokwemathematika kwaye sixoxe nganye ngeenkcukacha ezincinci. Ulawulo olulungelelanisiweyo luhambelana nomqondiso wempazamo; ngolo hlobo, yimpendulo ethe ngqo kumqondiso wempazamo oveliswe yisekethe:
? = ???(?)
Ukuzuza okukhulu ngokulinganayo kubangela utshintsho olukhulu ekuphenduleni impazamo, kwaye ngaloo ndlela kuchaphazela isantya apho umlawuli unokuphendula utshintsho kwinkqubo. Ngelixa inzuzo ephezulu ehambelanayo inokubangela ukuba isekethe iphendule ngokukhawuleza, ixabiso eliphezulu kakhulu linokubangela i-oscillations malunga nexabiso le-SP. Ixabiso eliphantsi kakhulu kwaye isekethe ayikwazi ukuphendula ngokufanelekileyo kwiinguqu kwisistim. Ulawulo oludityanisiweyo luhamba inyathelo elingaphaya kunenzuzo elinganayo, njengoko ilingana kungekhona nje ubukhulu besignali yempazamo kodwa kunye nobude bayo nayiphi na impazamo eqokelelweyo.

Ulawulo oludityanisiweyo lusebenza kakhulu ekwandiseni ixesha lokuphendula lesekethe kunye nokuphelisa impazamo yemeko ezinzileyo ehambelana nolawulo olulungelelanisiweyo. Ngokwenyani, ulawulo oludityanisiweyo luba phezu kwayo nayiphi na impazamo engalungiswanga ngaphambili, kwaye emva koko iphinda-phinda loo mpazamo ngo-Ki ukuvelisa impendulo edibeneyo. Ke, nakwimpazamo encinci ezinzileyo, impendulo enkulu edibeneyo edibeneyo inokufezekiswa. Nangona kunjalo, ngenxa yempendulo ekhawulezayo yolawulo oludibeneyo, ixabiso eliphezulu lenzuzo linokubangela ukugqithiswa okukhulu kwexabiso le-SP kwaye likhokelela kwi-oscillation kunye nokungazinzi. Iphantsi kakhulu kwaye isiphaluka siya kucotha kakhulu ekuphenduleni utshintsho kwinkqubo. Iinzame zolawulo lwe-derivative zokunciphisa ukudubula okugqithisileyo kunye nokukhala kokukhala kulawulo olulungelelanisiweyo kunye noludibeneyo. Imisela ukuba isiphaluka sitshintsha ngokukhawuleza kangakanani ixesha (ngokujonga i-derivative yesiginali yempazamo) kwaye iphinda-phinde nge-Kd ukuvelisa impendulo ephuma kuyo.

Ngokungafaniyo nolawulo olulinganayo kunye oludibeneyo, ulawulo oluphumayo luya kucotha impendulo yesekethe. Ngokwenza oko, iyakwazi ukubuyisela ngokuyinxenye i-overshoot kunye no-damp khupha nakuphi na ukujika okubangelwa lulawulo oludityanisiweyo nolulungelelanisiweyo. Amaxabiso okuzuza okuphezulu abangela ukuba isekethe iphendule kancinci kwaye inokushiya umntu echaphazeleka kwingxolo kunye ne-oscillation ephezulu (njengoko isekethe icotha kakhulu ukuphendula ngokukhawuleza). Iphantsi kakhulu kwaye isiphaluka sityekele ekugqithiseni ixabiso leengongoma ezimiselweyo. Nangona kunjalo, kwezinye iimeko ukugqithiswa kwexabiso lendawo emiselweyo ngayo nayiphi na imali ebalulekileyo kufuneka kuphetshwe kwaye ngaloo ndlela inzuzo ephezulu ephuma kuyo (kunye nenzuzo ephantsi yomlinganiselo) ingasetyenziswa. Itshathi engezantsi ichaza imiphumo yokwandisa inzuzo yayo nayiphi na iparameters ngokuzimeleyo.

Abalawuli beeNkonzo zeXesha Elikhethekileyo 

Ubume beDatha
Umlawuli we-PID kwi-DSC1 ufumana i-16-bit ADC sample, okuyinani lokubhinari eliphuma kwi-offset, elinokusuka ku-0-65535. Iimephu ze-0 ngokulandelelana kwigalelo elibi le-4V kunye ne-65535 imele i-+4V yesiginali yokufaka. Umqondiso "wempazamo", ?[?], kwiluphu ye-PID ngexesha elithile ? kumiselwa njenge?[?] = ? − ?[?] Phi? yindawo yokumisela kwaye ?[?] ngumqulutagesample kwi-offset yokubini isikali kwinqanaba elicacileyo lexesha, ?.

Ulawulo loMthetho kwiDomain yeXesha
Amagama amathathu enzuzo ayabalwa aze adityaniswe kunye.
?[?] = ??[?] + ??[?] + ??[?] ?? = ???[?] ?? ≈ ?? ∫ ?[?] ?? = ??(?[?] − ?[? − 1])
phi ??, ??, kwaye ?? Ngamanqwanqwa alinganayo, adityanisiweyo, kunye nenzuzo ephuma kuyo.

Ukusondela kwiNdibaniselwano kunye neNxulumano
I-DSC1 iqikelela ukuba isihlanganisi esine-accumulator.
∫ ?[?] = ?[?] + ∫ ?[? − 1] Uqwalaselo lwekhefu lohlanganiso, ububanzi bexesha, lisongelwe kwi- integral gain coefficient ?? njengokuba: ?? = ?′?ℎ
Phi ?'? yinzuzo edibeneyo ebizwa ngokuba yi- integral gain coefficient kwaye ℎ lixesha eliphakathi kwe-ADCsamples. Senza uqikelelo olufanayo kwi-derivative njengomahluko phakathi kwe-?[?] kunye ne-?[? − 1] kwakhona ucinga ukuba ?? ikwaqulethe i-1 / h yokukala.

Njengoko bekukhankanyiwe ngaphambili, ngoku qwalasela ukuba uqikelelo oludityanisiweyo noluphuma kwezinye aluqukanga naluphi na uqwalaselo lwexesha (s).ample interval), emva koku ℎ. Ngokwemveli sithi ulandelelwano lokuqala, olucacileyo, uqikelelo kuguqulo?[?] nge = ?(?, ?) ngokusekelwe kwimiqathango ekuluhlu lweTaylor ukwandiswa ngu ?[?] ≈ ?[? − 1] + ℎ ?(?, ?)
Oku kudla ngokubizwa ngokuba yi-Backward Euler Integration Scheme okanye i-Capcic First-Order First Numerical Integrator. Ukuba sisombulula i-derivative, ?(?, ?), sifumana:

Qaphela ukufana kwenani elingasentla kuqikelelo lwethu oluqhubekayo kwi-derivative kwi-equation yolawulo. Oku kuthetha ukuba, uqikelelo lwethu kwi-derivative sikalwa ngokufanelekileyo ngu-ℎ−1.

Ikwalinganisa iTheorem eyiSiseko yeCalculus ngokuchanekileyo:

Ngoku ukuba sithi? ludibaniso lophawu lwemposiso?, singenza olu tshintsho lulandelayo.
?[?]=∫?[?] ?(?,?)= ?[?] Kwaye sifumana kuluhlu lokuqala lukaTaylor uqikelelo lomsebenzi?: ∫?[?]=∫?[?−1]+ℎ ?(?)
Ngokuthatha nje u-∫?[?]=0 ka-?=0, uqikelelo oluqhubekayo kwisihlanganisi ngokoqobo lujiya kwi-accumulator.

Ke ngoko sihlengahlengisa ukuvela kwethu kwangaphambili komthetho wolawulo ukuba:

Umthetho wolawulo kwi-Frequency Domain
Nangona i-equation ethathwe kwicandelo eliqhubekayo ikwazisa ukuziphatha kwexesha le-domain ye-discrete-time controller ye-PID ephunyezwe kwi-DSC1, ithetha okuncinci malunga nempendulo ye-domain frequency yomlawuli. Endaweni yoko sazisa i-? i-domain, efana ne-domain ye-Laplace, kodwa ye-discrete kunexesha eliqhubekayo. Ngokufana noguqulo lweLaplace, uguqulo luka-Z lomsebenzi lukholisa ukumiselwa ngokuhlanganisa ubudlelwane benguqu ye-Z ekwitheyibhile, endaweni yokubeka inkcazo yenguqu ka-Z (eboniswe ngezantsi) ngokuthe ngqo.

Phi ingaba iradiyasi (ehlala iphathwa njenge-1) yotshintsho oluzimeleyo?, ? yingcambu ka -1, kwaye ∅ yimpikiswano entsonkothileyo kwiiradians okanye izidanga. Kule meko, zimbini kuphela iinguqu ezikwitheyibhile ze-Z eziyimfuneko.
?[?] = ?[?] ?[? − 1] = ?[?]?−1
I-Z-transform ye-proportional term, ??, ayinanto. Kwakhona, nceda wamkele okomzuzwana ukuba kuluncedo kuthi ukumisela imposiso ukulawula umsebenzi wogqithiselo, ?(?), kunokuba ngokulula ?(?).

I-Z-transform yegama elidibeneyo, ??, inomdla ngakumbi.
Khumbula iskimu sethu sokudityaniswa kwe-Euler ecacileyo kwicandelo langaphambili: ??(?) = ?? ∫ ?[?] = ?? (∫ ?[? − 1] + ℎ ?(?))
∫ ?(?) = ∫ ?(?) ?−1 + ℎ?(?)
∫ ?(?) − ∫ ?(?) ?−1 = ℎ?(?)

Okokugqibela, sijonga inzuzo ephuma kuyo, ??: 

Ukudibanisa umsebenzi ngamnye kule ingentla, sifika apha: 

Ngale equation, sinokubala ngokwenani impendulo yesizinda se-frequency yomlawuli kwaye siyibonise njengeploti ye-Bode, njengezantsi.
PID Transfer Functions, Kp = 1.8, Ki = 1.0, Kd = 1E-4

Qaphela indlela isilawuli se-PI esizuza ngayo sisondela kuphela kwinzuzo elinganayo kunye ne-hi-frequency kunye nendlela umlawuli wePD azuza ngayo indlela yokuzuza ngokulinganayo kwiifrikhwensi eziphantsi.

PID Tuning
Ngokubanzi, iinzuzo ze-P, I, kunye no-D ziya kufuneka zihlengahlengiswe ngumsebenzisi ukuze kulungiswe ukusebenza kwenkqubo. Ngelixa kungekho mithetho imileyo malunga nokuba amaxabiso afanele ukuba yintoni na kuyo nayiphi na inkqubo ethile, ukulandela iinkqubo ngokubanzi kufuneka kuncede ekulungiseni isekethe ukuze ihambelane nenkqubo yomntu kunye nokusingqongileyo. Ngokubanzi, isekethe ye-PID elungelelaniswe kakuhle iya kuthi kratya ngaphezulu kwexabiso le-SP kancinane kwaye ngokukhawuleza damp ngaphandle ukufikelela kwixabiso le-SP kwaye ubambe ngokuthe nkqi kuloo ndawo. Ilophu yePID inokutshixa nokuba kwithambeka elilungileyo okanye elibi ngokutshintsha uphawu lwe P, I, kunye no D iinzuzo. Kwi-DSC1, iimpawu zitshixiwe kunye ngoko ke ukutshintsha enye kuya kuzitshintsha zonke.

Ulungelelwaniso lwezandla lwezicwangciso zenzuzo yeyona ndlela ilula yokuseta ulawulo lwePID. Nangona kunjalo, le nkqubo yenziwa ngokusebenzayo (umlawuli we-PID oqhotyoshelwe kwisistim kunye ne-loop ye-PID inikwe amandla) kwaye ifuna isixa esithile samava ukuphumeza iziphumo ezilungileyo. Ukukhuphela isilawuli sakho se-PID ngesandla, qala ngokuseta okudityanisiweyo kunye neenzuzo eziphuma kwi-zero. Yandisa inzuzo elinganayo ude ubone i-oscillation kwimveliso. Inzuzo yakho ngokomlinganiselo kufuneka imiselwe kuqikelelo lwesiqingatha seli xabiso. Emva kokuba umlinganiselo wenzuzo usetiwe, nyusa inzuzo edityanisiweyo de kube nayiphi na i-offset ilungiswe kwisikali sexesha esifanelekileyo kwinkqubo yakho.

Ukuba ukonyusa le nzuzo kakhulu, uya kubona ukugqithiswa okukhulu kwexabiso le-SP kunye nokungazinzi kwisekethe. Nje ukuba inzuzo edibeneyo imiselwe, inzuzo ephuma kuyo inokunyuswa. Inzuzo ephuma kwi-derivative iya kunciphisa i-overshoot kunye damp inkqubo ngokukhawuleza kwixabiso lendawo emiselweyo. Ukuba unyusa inzuzo ephumayo kakhulu, uya kubona i-overshoot enkulu (ngenxa yokuba isekethe icotha kakhulu ukuphendula). Ngokudlala ngoseto lwenzuzo, unokwandisa ukusebenza kwesekethe yakho yePID, okukhokelela kwinkqubo ephendula ngokukhawuleza kutshintsho kwaye ngempumelelo damps ngaphandle kwe-oscillation malunga nexabiso lenqaku elimiselweyo.

Udidi Lolawulo	Kp	Ki	Kd
P	0.50 Ku	–	–
PI	0.45 Ku	1.2 Kp/Pu	–
PID	0.60 Ku	2 Kp/Pu	KpPu/8

Ngelixa ukulungiswa kwesandla kunokusebenza kakhulu ekuseteni isekethe ye-PID kwinkqubo yakho ethile, ifuna amava athile kunye nokuqonda kweesekethe ze-PID kunye nempendulo. Indlela ye-Ziegler-Nichols yokulungisa i-PID inikezela ngesikhokelo esicwangcisiweyo ngakumbi sokuseta amaxabiso e-PID. Kwakhona, uyakufuna ukuseta okudityanisiweyo kunye nenzuzo ephuma kwi-zero. Ukwandisa inzuzo elinganayo de isekethe iqale ukujikeleza. Siza kubiza eli nqanaba lokuzuza Ku. I-oscillation iya kuba nexesha lePu. Iinzuzo zezesekethe zolawulo ezahlukeneyo zinikwe kwitshathi engentla. Qaphela ukuba xa usebenzisa iZiegler-Nichols indlela yokulungisa nge DSC1, ixesha elidityanisiweyo eligqitywe kwitheyibhile kufuneka liphindaphindwe ngo 2⋅10-6 ukuqhelanisa ukuya kwiample ireyithi. Ngokufanayo, i-coefficient yokuphuma kufuneka yahlulwe ngo-2⋅10-6 ukuqhelanisa ukuya kwi-s.ampumyinge.

Rampnge
Abasebenzisi banokufuna ukumisela indawo yokusebenza yomqondiso omkhulu okanye indawo eluncedo yokumisela inkqubo. Ukumisela indawo yokusebenza yomqondiso omkhulu (emva koku ekubhekiselwa kuyo njenge-DC offset) okanye eyona ndawo ifanelekileyo yokumisela i-servo, ubuchule obuqhelekileyo kukuvuselela inkqubo ngokuphinda-phindeneyo ngevolthi eyonyuka ngomgca.tage umqondiso. Ipateni ngokuqhelekileyo ibizwa ngokuba yi-sawtooth-wave, ngenxa yokufana kwayo namazinyo e-saw.

Imowudi yokuTshixa
Imowudi yokutshixa ephezulu iphumeza i-algorithm yokutshixa i-dither eyaziwa ngokuba ngumlawuli ofuna ngokugqithisileyo. Kule ndlela yokusebenza, ixabiso lolawulo libekwe phezulu kwimveliso ye-sine wave. Igalelo elilinganisiweyo voltage yokuqala yedijithali high-pass ehluzwayo (HPF) ukususa nayiphi na i-DC offset. Emva koko umqondiso odityanisiweyo we-AC wehliswa ngokuphindaphinda umthamo ngamnye olinganisiweyotage ngexabiso loguqulo lwamaza e-sine ephumayo. Lo msebenzi wokuphindaphinda wenza umqondiso othotyiweyo kunye namacandelo amabini aphambili: i-sine wave kwisimbuku seefrikhwensi ezimbini kunye nomqondiso kumahluko wefrikhwensi ezimbini.

Isihluzo sedijithali sesibini, ngeli xesha sisihluzo sokupasa esisezantsi (LPF), sinciphisa isixa se-a-two-emibini yefrikhwensi, kwaye sisasaza umahluko ophantsi wamatyeli amabini. Isiqulatho somqondiso kwifrikhwensi efanayo njengoko ukumodareyitha kubonakala njenge-DC signal post demodulation. Isinyathelo sokugqibela kwi-algorithm ye-lock lock kukudibanisa isignali ye-LPF. Isiphumo sokudibanisa, sidityaniswe nemodyuli ephumayo, iqhuba i-voltage yemvelisotage. Ingqokelela yamandla ophawu asezantsi athotyiweyo kwisihlanganisi sityhala i-offset control voltagi-e yemveliso ephezulu nangaphezulu de uphawu lwemveliso ye-LPF lujike kwaye imveliso yomhlanganisi iqala ukuncipha. Njengoko ixabiso lolawulo lisondela kwincopho yempendulo yenkqubo, isiphumo sokumodareyitha kwisiginali yegalelo kwisilawuli se-servo siba sincinci kwaye sincinci, ekubeni i-slope yefom ye-sinusoidal wave i-zero kwincopho yayo. Oku kuthetha ukuba kukho ixabiso eliphantsi lemveliso ukusuka kwi-low-pass-filtered, isignali ethotyiweyo, kwaye ngoko ke ngaphantsi ukuqokelela kwi- integrator.

Umzobo 12 Umzobo webhloko yesilawuli sokutshixa okuphezulu. Umqondiso wegalelo ovela kwisityalo esiphezulu esiphendulayo sifakwe kwidijithali, emva koko sihluzwe ukugqithisa okuphezulu. Isignali yemveliso ye-HPF ithotywe nge-oscillator yendawo yedijithali. Imveliso ye-demodulator ihluzwa-ipasi eliphantsi kwaye ihlanganiswe. Isiphumo sokuhlanganisa songezwa kwisiginali yokumodareyitha kunye nesiphumo kwisityalo esisabelayo esiphakamileyo. I-Peak yokutshixa i-algorithm elungileyo yokulawula ukukhetha xa inkqubo umsebenzisi anqwenela ukuyilawula ingenayo impendulo ye-monotonic malunga neyona ndawo yokulawula. EksampIintlobo zolu didi lweenkqubo yimidiya ebonayo enobude bewavevele ephumayo, njengeseli yomphunga, okanye iRF band-reject filter (notch filter). Uphawu olusembindini weskimu solawulo lokutshixa kwincopho kukuthambekela kwe-algorithm yokulawula inkqubo ngokubhekiselele kwi-zero-yokuwela umqondiso wempazamo ohambelana nencopho yomqondiso olinganisiweyo, njengokungathi umqondiso wephutha wawuphuma kumqondiso olinganisiweyo. Qaphela ukuba incopho inokuthi ibe ntle okanye ibembi. Ukuqalisa ngencopho yokutshixa imo yokusebenza ye-DSC1, unokulandela le nkqubo.

1. Qinisekisa ukuba kukho incopho (okanye intlambo) yomqondiso otshixayo ngaphakathi kumthamo wolawulotage uluhlu lwe actuator, kunye nokuba indawo encophoyo izinzile ngokwexesha. Kuluncedo ukusebenzisa i-RAMP imowudi yokubona umqondiso phezu komthamo wolawulotage uluhlu lomdla.
2. Qaphela umthamo wolawulotage indawo yencopho (okanye intlambo).
3. Qikelela ukuba ibanzi kangakanani incopho (okanye intlambo) kulawulo voltage kwisiqingatha somphakamo wencopho. Obu bubanzi, bungama-volts, buqhele ukubizwa ngokuba yi-Full-Width Half-Max okanye i-FWHM. Kufuneka ubuncinane ibe yi-0.1V ububanzi ngeziphumo ezilungileyo.
4. Seta uhlengahlengiso amplitude (A) ukuya kwi-1% ukuya kwi-10% ye-FWHM voltage.
5. Seta i-offset voltage ngokusondeleyo kangangoko kwindawo yencopho (okanye intlambo) onqwenela ukutshixa kuyo.
6. Seta i-modulation frequency kwi-frequency oyifunayo. Kwisikrini sokuchukumisa oku kuchaphazeleka nge-M, iparamitha yokumodulation frequency. I-modulation frequency yi-100 Hz amaxesha M. Olona khetho lungcono lokumodareyitha luxhomekeke kwisicelo. I-Thorlabs icebisa amaxabiso ajikeleze i-1 kHz kwi-actuator yoomatshini. Iifrikhwensi eziphezulu zinokusetyenziselwa ii-electro-optic actuators.
7. Cwangcisa i-peak lock integral coefficient (K) ukuya ku-0.1 umphinda-phinde ngo-A. K inokuba ntle okanye ingabinayo. Ngokubanzi, i-K itshixa kwincopho yomqondiso wegalelo, ngelixa i-negative K itshixa kwintlambo yophawu logalelo. Nangona kunjalo, ukuba i-actuator okanye inkqubo etshixiweyo inokulibaziseka kwesigaba esingaphezulu kwama-90 kwi-dither frequency, uphawu lwe-K luya kuguqula kwaye i-positive K iya kutshixa kwintlambo, kwaye i-negative K iya kutshixa ukuya kwincopho.
8. Cofa u-Run kwaye uqinisekise ukuba umthamo wolawulotage imveliso iyatshintsha ukusuka kwixabiso loqobo (O) kwaye alibaleki ligqithise. Kungenjalo, jonga inkqubo eguquguqukayo usebenzisa i-oscilloscope ukuqinisekisa ukuba i-DSC1 itshixekile kwincopho okanye intlambo enqwenelekayo.

Isazobe 13 Eksample data evela rampukungenisa isiphumo sokunciphisa umthamotage kunye ne-sine wave eqhubekayo, enyanzeliswe kwisityalo sokuphendula esiphezulu. Qaphela impazamo yomqondiso we-zero wokuwela ihambelana nencopho yomqondiso wempendulo yesityalo.

ULondolozo kunye nokuCoca
Ucoce rhoqo kwaye ugcine i-DSC1 ukuze usebenze ngokugqibeleleyo. I-DSC1 ayifuni kugcinwa rhoqo. Ukuba isikrini esichukumisayo kwisixhobo simdaka, i-Thorlabs icebisa ngononophelo ukucoca isikrini sokuchukumisa ngelaphu elithambileyo, elingena-lint, elizaliswe butywala be-isopropyl.

Xa usebenzisa i-GUI yedesktop, umlawuli we-servo kufuneka aqhagamshelwe ngentambo ye-USB 2.0 (ebandakanyiweyo) ukusuka kwi-port yedatha yesixhobo ukuya kwi-PC ene-software ye-Digital Servo Controller efakwe.

Iiluphu eziphantsi komhlaba kunye ne-DSC1
I-DSC1 ibandakanya ukujikeleza kwangaphakathi ukucutha ukubakho kokwenzeka kweelophu emhlabeni. I-Thorlabs icebisa ukuba kusetyenziswe i-transformer eyodwa ye-DS5 elawulwayo yonikezelo lwamandla okanye ipakethi yebhetri yangaphandle ye-CPS1. Kunye nokuba yi-DS5 okanye i-CPS1 yobonelelo lwamandla, umgangatho womqondiso ngaphakathi kwe-DSC1 udada malunga nomhlaba wokuphuma eludongeni. Ekuphela koqhagamshelo kwisixhobo esiqhelekileyo kulo mhlaba womqondiso yintsimbi yomhlaba yomqondiso we-USB-C isidibanisi samandla kunye nomphandle, indlela yokubuyisela kwisiphumo se-SMB coaxial cable. Uqhagamshelwano lwedatha ye-USB lodwa. Isiginali yegalelo inesixhasi sokunqanda i-loop-ground-loop phakathi kwendlela yokubuyisela umqondiso kunye nomhlaba wesignali ngaphakathi kwesixhobo esithintela ukuphazamiseka kwe-loop yomhlaba. Okubalulekileyo, azikho iindlela ezimbini ezithe ngqo kumhlaba wesignali yesixhobo, ukunciphisa ukwenzeka kweelophu zomhlaba.

Ukunciphisa ngakumbi umngcipheko wokuphazamiseka kwe-loop yomhlaba, i-Thorlabs icebisa ezi ndlela zilandelayo: 

• Gcina onke amandla kunye neentambo zomqondiso kwisixhobo zimfutshane.
• Sebenzisa nokuba yibhetri (CPS1) okanye i-transformer eyodwa (DS5) unikezelo lwamandla kunye ne-DSC1. Oku kuqinisekisa umgangatho wesixhobo esidadayo.
• Musa ukudibanisa iindlela zezinye izixhobo zokubuyisela umqondiso kwenye.
  • Ex eqhelekileyoample yi-benchtop oscilloscope eqhelekileyo; amaxesha amaninzi amaqokobhe angaphandle odibaniso lwegalelo leBNC adityaniswe ngokuthe ngqo kumhlaba womhlaba. Iikliphu ezininzi zomhlaba ezidityaniswe kwindawo efanayo yomhlaba kumfuniselo zinokubangela iluphu yomhlaba.

Nangona i-DSC1 kungenakwenzeka ukuba ibangele i-ground loop ngokwayo, ezinye izixhobo kwilebhu yomsebenzisi zisenokungabi nandawo yokwahlula iluphu ephantsi kwaye ke ngoko inokuba ngumthombo we-loop emhlabeni.

Ukunika amandla i-DSC1
I-DSC1 Digital Servo Controller ifuna amandla e-5 V nge-USB-C ukuya kuthi ga kwi-0.75 A incopho yangoku kunye ne-0.55 A ekusebenzeni okuqhelekileyo. I-Thorlabs inikezela ngezinto ezimbini ezihambelanayo zamandla: i-CPS1 kunye ne-DS5. Kwizicelo apho uvakalelo lwengxolo lunyanzelwa kancinane okanye apho amaxesha okusebenza angaphezu kweeyure ezisi-8 afuneka, unikezelo lombane olulawulwa yi-DS5 luyacetyiswa. Ubonelelo lwamandla ebhetri lwe-CPS1 luyacetyiswa xa kufunwa ukusebenza kwengxolo ngeyona ndlela. Nge-CPS1 ihlawuliswe ngokupheleleyo kwaye isempilweni entle, i-DSC1 inokusebenza iiyure ezisi-8 okanye ngaphezulu ngaphandle kokutshaja kwakhona.
