Iinjini ze-Servo zilawulwa ngokubanzi ziisekethe ezintathu, eziziinkqubo ezintathu ezivaliweyo zokulawula ingxelo engeyiyo yePID. Isekethe ye-PID yisekethe yangoku kwaye iphunyezwe ngaphakathi kwisilawuli se-servo. Imveliso yangoku esuka kumlawuli ukuya kwi-motor isekelwe kwitshekhi yezinto zeHolo, impendulo engalunganga ngoku isetyenzisiwe ngokusekelwe kwi-PID, kwaye i-output current ihlengahlengiswa ukuba isondele ngokusemandleni kwi-set current. Isekethe yangoku ilawula i-motor torque, ngoko ke umlawuli unemisebenzi encinci kunye neempendulo ezincinci zemihla ngemihla kwaye kufuneka akhawuleze kwimodi yokulawula i-torque. Nangona zininzi iindlela zolawulo ezikhoyo kwi-servo motor, iGator Precision, enye ye-10 ephezulu yaseTshayinaiifektri zerotor ezanelisayoukudibanisa ukwenziwa komngundo, isitampu se-silicon yentsimbi, ukudityaniswa kwemoto, imveliso kunye nokuthengisa, apha kuya kuthetha ngeendlela ezintathu ezisetyenziswa kakhulu zokulawula kwi-servo motor.
Iindlela zokulawula eziphambili kwi-servo motor ziquka imo yokulawula i-torque, imo yokulawula indawo kunye nemodi yesantya.
1. Imo yokulawula iTorque. Kule ndlela, i-torque ephumayo ye-motor shaft isetwa ngegalelo langaphandle le-analog okanye idilesi ethe ngqo. Ngokomzekelo, i-torque ephumayo ye-motor shaft yi-2.5Nm xa i-analog yangaphandle isethelwe kwi-5V. Xa i-motor ijikeleza kunye nomthwalo we-shaft ngaphantsi kwe-2.5Nm kunye nomthwalo wangaphandle ulingana no-2.5nm (ngaphezu kwe-2.5nm), i-motor inzima ukuyijikeleza. Xa i-servo motor ibuyisela umva (ngokubanzi phantsi komthwalo wamandla), ukusetwa kobuninzi be-analog kunokutshintshwa ngexesha langempela ngokuguqula i-torque setting okanye ngokutshintsha ixabiso ledilesi yesihlobo ngokonxibelelwano.
2. Imo yokulawula indawo. Imo yokulawula indawo ngokubanzi ichaza umlinganiselo wesantya ngokusebenzisa i-pulse frequency yegalelo langaphandle kunye nembono ngenani le-pulses. Isantya kunye nokunciphisa abanye abaqhubi beemoto ze-servo banokwabelwa ngokuthe ngqo ngonxibelelwano. Kule modi, isantya kunye nendawo inokulawulwa ngokungqongqo, ngoko ke indlela yokulawula indawo isetyenziswa ngokubanzi ekubekeni iileyile ze-CNC kunye nezixhobo zoshicilelo.
3. Imo yesantya. Isantya sinokulawulwa ngokwegalelo le-analog okanye i-pulse frequency frequency. Xa i-PID yangaphandle yolawulo lwesixhobo sokulawula ingasetyenziswa, imowudi yesantya nayo inokubekwa, kodwa qiniseka ukuba ukondla umqondiso wedatha yesikhundla semoto okanye umthwalo othe ngqo ukuya kwinqanaba eliphezulu lokusebenza.Iinkampani eziphambili zeServo motor rotorFumana imowudi yesikhundla nayo iyasebenza kwicala langaphandle lomthwalo othe ngqo ukujonga isiginali yedatha yendawo, apho kuphela isantya semoto sijongiwe kwicala le-servo motor shaft, kwaye umqondiso wedatha yesikhundla unikwa isixhobo sokujonga ngokuthe ngqo kwisixhobo. icala lomthwalo. Ngokwenza njalo, ukutenxa kwi-intermediate drive kuya kuncitshiswa kwaye ukuchaneka kokubeka inkqubo yonke kuya kuphuculwa.
