摘要
通过分析开关磁阻电机的转矩脉动问题,设计了基于滑模变结构的速度和电流调节器,建立带有趋近律的控制方法,讨论了变结构控制的到达条件与稳定条件,在此基础上,完成开关磁阻电机的滑模变结构控制。利用Matlab软件对控制方案进行了仿真实验;结果表明,相对于传统控制规律,滑模变结构控制在无需电机精确模型的情况下,能够达到预期的控制要求,调节器正常工作,有效抑制了电机的转矩脉动。
This paper analyzed the problem of torque tipples for Switched Reluctance Motor (SRM),designed speed and current regulator based on sliding mode variable structure,established control method with reaching law,and discussed the reaching condition and stability conditions for variable structure control.Based on those,the control of a switched reluctance motor using variable structure is completed.The simulation experiment of the control scheme shows that the sliding mode variable structure for SRM achieved the expected control requirements without an accurate motor model.The regulators effectively suppress the torque ripple of the motor.
