基于二阶滑模观测器的永磁同步电动机伺服控制

Second Order Sliding Mode Observer Design for PMSM Servo Control

针对永磁同步电动机设计了一种二阶滑模观测器,Super-Twisting算法被用于在动态观测系统中产生二阶滑模状态。采用二阶滑模观测器的优点是可以避免普通一阶滑模技术中的抖动问题,而抖动现象是普通滑模技术所固有的,该方法对永磁同步电动机的控制效果通过Matlab/Simulink进行了仿真实验。

The sliding mode control for permanent magnet synchronous motors （PMSM） was designed. The so - called super - twisting algorithm was utilized for generating the second order mode in the observer dynamical system. The main advantage of the use of high order sliding mode techniques was that it avoided the chattering phenomenon which was inherent to the classical first order sliding mode observers and controllers. The efficiency of the proposed observers was illustrated on a Matlab/Simulink.
