摘要
永磁同步电动机在某些参数及工作条件下会出现混沌运动,这将危及电动机系统的稳定运行,并且会损坏电动机,因此如何抑制或消除永磁同步电动机的混沌运动成为保持其稳定性的关键问题。本文采用条件负反馈方法对永磁同步电动机混沌模型进行控制,数值研究结果表明控制简单有效,能将系统控制到接近于原来的不稳定平衡点,并且可以使电动机d轴的电流不随控制参数的变化而变化,具有重要的工程意义。
The permanent magnet synchronous motor （PMSM） has behavior chaos with some parameters or under certain working conditions which threaten the secure and stable operation of motor drive and destroy the motor. Hence, it is important to study the method of controlling or suppressing chaos in PMSM. We designed a conditioned negative feedback controller to eliminate chaos in PMSM. Simulation results show that the designed controller is effective. The research results have high value in maintaining the system＇s secure operation.
