| 摘 要： | 开关磁阻电机(SRM)具有转矩脉动较大的特点。提出一种结合滞环控制和脉宽调制(PWM)的直接瞬时转矩控制策略解决此类问题。分析了转矩在控制过程中出现大波动的机理,制订了单相区和换相区不同控制方法。考虑到转矩在不同条件下输出特性,将PWM等效策略引入滞环限间,优化了转矩控制效果。加入了模糊自适应PID控制器,提高系统响应性能。仿真结果表明该控制策略响应速度快,能有效地抑制SRM的转矩脉动。

| Abstract: | Switched reluctance motor (SRM) had the characteristics of torque ripple. A direct instantaneous torque control strategy combining hysteresis control and pulse width modulation (PWM) was proposed. Based on the analyses on the mechanism of large fluctuations in torque during control process, different control methods were formulated for singlephase and commutation zones. Considering the output characteristics of torque under different conditions, the PWM equivalent strategy was introduced into the hysteresis limit interval to optimize the torque control effect. Fuzzy adaptive PID controller was added to improve the response performance of the system. The simulation results showed that the control strategy had a fast response and could suppress the torque ripple of the SRM effectively. |
