A Sliding Mode Observer Design for Permanent Magnet Synchronous Motors

介绍了一种用于永磁同步电动机控制的滑模观测器设计方法,针对滑模控制固有的抖动问题,引入了伪滑模控制。在滑模观测器原理设计中,证明了系统Lyapunov函数渐进稳定,同时对系统进行了仿真,结果表明永磁同步电动机在参数摄动下具有较好的鲁棒性和动态性能。

A kind of method about sliding mode observer used in permanent magnet synchronous motors（PMSMs） was introduced in this paper.Due to the inherent chattering problem existing in the sliding mode,this paper proposed a pseudo sliding mode control.In the design of the sliding mode observer,it is proved that Lyapunov function of system is asymptotic stable.Simulation results show that PMSM has robustness as well as precision in spite of parameter uncertainty.
