A i-servo motoriyinjini engakwazi ukulawula ngokunembile indawo, isivinini, kanye nokusheshisa futhi ngokuvamile isetshenziswa ezinhlelweni ezidinga ukulawula ukunyakaza okunembe kakhulu. Kungaqondwa njengemoto elalela umyalo wesignali yokulawula: ngaphambi kokuba isignali yokulawula ikhishwe, i-rotor imile; Lapho isignali yokulawula ithunyelwa, i-rotor ijikeleza ngokushesha; Uma isignali yokulawula ilahlekile, i-rotor ingamisa ngokushesha. Umgomo wayo wokusebenza ubandakanya isistimu yokulawula, isifaki khodi kanye neluphu yempendulo. Okulandelayo yincazelo enemininingwane yokuthi ama-servo motors asebenza kanjani:
Uhlelo lokulawula: Uhlelo lokulawula lwe-servo motor ngokuvamile luqukethe isilawuli, umshayeli kanye nemoto. Isilawuli sithola amasignali okulawula avela ngaphandle, njengeziyalezo zendawo noma imiyalelo yesivinini, bese siguqula lawa masignali abe amasignali amanje noma ama-voltage bese ewathumela kumshayeli. Umshayeli ulawula ukujikeleza kwenjini ngokwesiginali yokulawula ukuze afinyelele indawo edingekayo noma ukulawula isivinini.
Isifaki khodi: Ama-Servo motors ngokuvamile ahlonywa ngesishumeki ukuze kulinganiswe indawo yangempela ye-motor rotor. I-encoder ibuyisela ulwazi lwendawo ye-rotor ohlelweni lokulawula ukuze uhlelo lokulawula lukwazi ukuqapha indawo yemoto ngesikhathi sangempela futhi lulungise.
Iluphu yempendulo: Isistimu yokulawula yama-servo motors imvamisa ithatha isilawuli se-loop evaliwe, esilungisa ukuphuma kwenjini ngokuqhubekayo ukulinganisa indawo yangempela nokuqhathanisa nendawo oyifunayo. Le luphu yempendulo iqinisekisa ukuthi ukuma kwemoto, isivinini, nokusheshisa kuyahambisana nesiginali yokulawula, okuvumela ukulawula ukunyakaza okunembayo.
I-algorithm yokulawula: Isistimu yokulawula ye-servo motor ngokuvamile isebenzisa i-PID (i-proportional-integral-derivative) yokulawula i-algorithm, elungisa ngokuqhubekayo ukuphuma kwemoto ukuze yenze indawo yangempela ibe seduze ngangokunokwenzeka endaweni oyifunayo. I-algorithm yokulawula ye-PID ingalungisa okukhiphayo kwemoto ngokusekelwe kumehluko phakathi kwendawo yangempela nendawo oyifunayo ukuze kuzuzwe ukulawula ukuma okunembile.
Emsebenzini wangempela, lapho isistimu yokulawula ithola imiyalelo yendawo noma isivinini, umshayeli uzolawula ukujikeleza kwemoto ngokusekelwe kule miyalo. Ngesikhathi esifanayo, isifaki khodi siqhubeka nokukala isikhundla sangempela se-rotor ye-motor futhi siphakela lolu lwazi emuva ohlelweni lokulawula. Isistimu yokulawula izolungisa okukhiphayo kwenjini nge-algorithm yokulawula ye-PID ngokusekelwe kulwazi lwendawo lwangempela olubuyiselwe isishumeki sekhodi, ukuze indawo yangempela ibe seduze ngangokunokwenzeka endaweni oyifunayo.
Isimiso sokusebenza se-servo motor singaqondwa njengesistimu yokulawula iluphu evaliwe eqhubekayo ukulinganisa isikhundla sangempela futhi isiqhathanise nendawo oyifunayo, futhi ilungise ukuphuma kwemoto ngokuvumelana nomehluko ukuze kuzuzwe isikhundla esinembile, isivinini kanye nokulawula ukusheshisa. Lokhu kwenza ama-servo motors asetshenziswe kabanzi ezinhlelweni ezidinga ukulawulwa kokunyakaza okunembayo okuphezulu, njengamathuluzi omshini we-CNC, amarobhothi, okokusebenza okuzenzakalelayo neminye imikhakha.
Ngokuvamile, isimiso sokusebenza se-servo motor sihilela ukusebenzisana kwesistimu yokulawula, i-encoder kanye ne-feedback loop. Ngokusebenzisana kwalezi zingxenye, ukulawula okunembile kwesimo semoto, isivinini kanye nokusheshisa kufinyelelwa.
