| 摘 要： | 在某些参数及工作条件下,非均匀气隙永磁同步电动机(PM SM)会出现混沌运动。混沌的存在将严重危及电机传动系统的稳定运行,因此如何抑制或消除PM SM中的混沌运动成为保持其稳定性的关键问题。利用线性状态反馈控制方法对PM SM的混沌运动进行控制,数值仿真结果表明:控制策略不仅行之有效,而且由于反馈增益由极点配置方法确定,因此具有很好的动态响应特性。研究结果对保证电机传动系统的稳定运行具有较好的参考价值。

| Abstract: | Recent research has indicated that the permanent magnet synchronous motor(PMSM) has non-smooth-air-gap behavior chaos with some parameters or under certain working conditions which threaten the secure and stable operation of motor drive.Hence,it is important to study the method of controlling or suppressing chaos in PMSM.Based on the pole assignment method,a state variable feedback controller was designed to eliminate chaos in PMSM.Simulation results show that the designed controller is effective and the control system is excellent in the dynamic response performance because of the feedback gain determined by pole-placement method.The research results have high value in maintaining the system's secure operation. |
