Torque-Ripple Minimization in Switched Reluctance Motor Based on Sinusoidal Model

提出了一种新的开关磁阻电动机输出转矩的正弦模型,基于正弦模型介绍了开关磁阻伺服电动机控制系统的输出转矩消脉动控制策略,并对上述的控制策略进行了仿真,最后以三相 (12／8)结构的开关磁阻伺服电动机为对象进行了相关实验。试验验证了该输出转矩消脉动方案的可行性。

A novel sinusoidal torque model of Switched Reluctance Motors（SRM） is presented in this paper. The control strategy of torque-ripple minimization for control system of Switched Reluctance Servo Motors based on fuzzy controllers is introduced. This paper also proposes simulation of the control strategies. Finally, correlative experiments are done with a 12/8 pole switched reluctance servo motor prototype. It shows that the strategy is feasible.
