Matlab based minimum variance tracking control for Switched Reluctance Motor

开关磁阻电机由于其具有结构简单、启动电流小、起动转矩大、运行可靠等优点,是电动汽车驱动电机的理想选择之一。首先建立了一种开关磁阻电机离散化数学模型;其次,提出了一种基于最小位置方差的控制策略。研究结果表明,采用本文方法能够实现带干扰的开关磁阻电机系统快速跟踪能力。

Switched reluctance motor(SRM)is one of the ideal choice for electric vehicle drive motor because of its simple structure,small starting current,large starting torque and reliable operation.Firstly,a discrete mathematical model of switched reluctance motor is established.Secondly,a control strategy based on minimum position variance is proposed.The results show that this method can realize the fast tracking ability of switched reluctance motor system with interference.
