I. Izimiso Zobuchwepheshe Eziyinhloko Zokulawula I-Torque: Kusukela Ekulungisweni Kwemishini Kuya Ekulawulweni Okuhlakaniphile Kwe-Loop Closed-Loop

Ubuchwepheshe bokulawula i-torque izikulufi zikagesi isuke ekulungisweni kwemishini kwendabuko yaya ohlelweni lokulawula oluhlakaniphile olunezinhlangothi eziningi. Umqondo wayo oyinhloko ukufeza ukulawula okunembile ngendlela evaliwe "yokufaka umyalo - ukuqapha kwesikhathi sangempela - ukulungiswa okuguquguqukayo."

1. Ukulawulwa Okuyisisekelo Kwemishini
Ukulawulwa kwe-torque kwasekuqaleni kwakuncike ekusebenzeni ngokomzimba kwe-clutch kanye ne-torsion spring: lapho i-torque yokukhipha ifinyelela umkhawulo ohleliwe, i-spring iyacindezela, ibangele ukuthi i-clutch ishelele futhi inqamule ukudluliselwa kwamandla ukuze kugwenywe ukulayisha ngokweqile. Le ndlela ilula ngesakhiwo futhi ifanele amathuluzi asezingeni lokuqala, kodwa ukunemba kwayo kuthinteka kakhulu ukukhathala kwe-spring, kanye nokuphambuka okuvame ukwedlula ±10%.

2. Ukuthuthukiswa Kokulawula Nge-elekthronikhi Amathuluzi esimanje asebenzisa kakhulu ubuchwepheshe bokulawula nge-elekthronikhi, okuyinhloko yalokhu okuhlanganisa: Ukulawula ukuzwela kwamanje: Ukuqapha izinguquko kumandla kagesi we-motor ukuze kunqunywe i-torque yomthwalo; ukunciphisa ngokuzenzakalelayo isivinini noma ukusika amandla lapho kufinyelelwa umkhawulo, ngesikhathi sokuphendula esingaba ngu-50ms; Ukuguqulwa kobubanzi be-PWM pulse: Ukufeza ukulawulwa kwesivinini esingenasinyathelo se-torque ngokulungisa umjikelezo womsebenzi we-voltage pulse, ukuthuthukisa ukunemba kwesimo esizinzile kube ngaphakathi kuka-±5%; Ubuchwepheshe bokulawula i-Vector: Ukuhlukanisa ugesi wamanje wokuvuselela (i-d-axis) kanye nogesi wamanje we-torque (i-q-axis) we-AC motor ngokusebenzisa ukuguqulwa kwe-Clark/Park coordinate, ukufeza ukulawula okuzimele nokunembile, kufinyeze isikhathi sokuphendula esishintshashintshayo sibe ngu-10-50ms.

3. Ukulawula Okuvaliwe Okuhlakaniphile
Amamodeli aphezulu ahlanganisa izinzwa ze-torque kanye nama-algorithms e-AI ukuze akhe iluphu ephelele evaliwe:
