提出了一种基于改良型趋近律方法的滑模控制策略来提高六相永磁同步电机调速系统的动态调节特性。使用该趋近律方法设计了一种六相永磁同步电动机滑模速度调节器并在Matlab上进行了仿真,通过与PI调节器的仿真结果比较,发现该速度控制器提高了六相永磁同步电机调速系统的快速性、稳定性、精度与鲁棒性,有效地抑制了PI控制下的超调。

This paper propose a sliding mode speed controller strategy based on improved reaching law metliod to improve the dynamic state adjust quality of six phase permanent magnet synchronous motor （PMSM）. Using this metliod design a sliding mode speed controller and carried out simulation on Matlab, comparing the simulation results with the PI controller, the result show that the improved speed controller improves the rapidity and stability accuracy and robustnes of t!ie six phase permanent magnet synchro-nous motor speed control system,it restrains the overs!ioot under PI control effectively.
