摘要:通過(guò)對(duì)開(kāi)關(guān)磁阻電機(jī)轉(zhuǎn)矩輸出特性的研究,提出一種電流斬波控制與瞬時(shí)直接轉(zhuǎn)矩控制相結(jié)合的改進(jìn)型SRM轉(zhuǎn)矩脈動(dòng)抑制算法。采用CCC可設(shè)定SRM最大相電流值并增大換相重疊角,減緩轉(zhuǎn)矩下降速度,簡(jiǎn)化轉(zhuǎn)矩分配算法。本文搭建了SRM的 Matlab/Simulink改進(jìn)型DITC轉(zhuǎn)矩脈動(dòng)抑制仿真平臺(tái)。結(jié)果表明在簡(jiǎn)化換相重疊角轉(zhuǎn)矩給定算法的同時(shí)可使SRM在安全允許范圍內(nèi)達(dá)到最佳轉(zhuǎn)矩脈動(dòng)抑制效果,具有實(shí)際應(yīng)用價(jià)值。

5總結(jié)分析
通過(guò)將CCC與DITC相結(jié)合,并重新定義換向重疊區(qū)轉(zhuǎn)矩給定算法,SRM調(diào)速系統(tǒng)達(dá)到了較好的控制效果。其中CCC控制既保證了SRM運(yùn)行于安全電流值內(nèi),又使轉(zhuǎn)矩下降速度減緩,為導(dǎo)通的下一相的轉(zhuǎn)矩給定提供一定的冗余空間,并簡(jiǎn)化換相重疊角內(nèi)轉(zhuǎn)矩給定算法。在實(shí)際運(yùn)行過(guò)程中,SRM調(diào)速系統(tǒng)并不需要在電動(dòng)區(qū)域內(nèi)全導(dǎo)通,例如12/8極SRM調(diào)速系統(tǒng),采用在0.5°到20°的范圍,負(fù)向轉(zhuǎn)矩小,轉(zhuǎn)矩脈動(dòng)值小,達(dá)到較好轉(zhuǎn)矩脈動(dòng)抑制效果。改進(jìn)型DITC具有算法簡(jiǎn)單,穩(wěn)定可靠的特定,具有實(shí)際應(yīng)用價(jià)值。
