摘要
造成电励磁双凸极电机转矩脉动的原因有很多,通过适当的控制策略可以优化某些因素从而改善转矩脉动。从控制策略方面总结了近年来优化转矩脉动的研究成果,介绍了几种有效的控制方法,大体思路可以从改善绕组相电流(包括稳定相电流、消去谐波电流、电流矢量分解等)、优化开关角度弥补换相电流缺陷以及优化输出转矩控制等方面来减小转矩脉动。
There are many factors cause torque ripple of doubly salient electro-magnetic motor. Appropriate control strategies can optimize some factors to improve torque ripple. The research achievements about torque ripple optimization from the control strategy in recent years were summarized, and some feasible methods was introduced to reduce torque rip- ple. The general ideas involve improving the winding current ( including stable phase current, elimination harmonic current, current vector decomposition, etc. ), optimizing the switch angle that made up in phase current defect and optimized output torque control, etc.
