基于改进型非奇异终端滑模观测器的永磁同步电动机矢量控制系统研究

摘要

Since the conventional sliding mode observer seems not satisfactory, after referring to the existing solutions, the improvement of the conventional SMO is presented based on two typical methods, having obtained good results. For the start-up problem, an open loop startup strategy with smooth transition is proposed, and the effectiveness of the scheme is veriifed by simulation.%针对传统滑模观测器的永磁同步电动机控制系统存在的抖振问题，在了解现有解决方案的基础上，应用两种典型方法对传统滑模观测器进行了改进，并对于永磁同步电动机的启动，给出了一种由开环启动到闭环运行平滑切换的自启动方案，最终通过仿真与实验验证了其有效性。
