摘要
研究永磁同步电动机离散位置跟踪控制问题.采用欧拉方法建立永磁同步电动机系统离散模型,利用模糊逻辑系统逼近系统中的非线性函数,同时基于反步法实现永磁同步电动机模糊离散控制.所提出的控制器可确保系统的跟踪误差收敛到原点的一个充分小的邻域内,实现了永磁同步电动机的位置跟踪控制.仿真结果验证了所提出方法的有效性.
This paper studies a fuzzy discrete -time position tracking control for a permanent magnet syn-chronous motor ( PMSM) .Fuzzy logic systems are used to approximate the nonlinearities of the discrete -time PMSM drive system which is derived by using the Euler method and a fuzzy discrete -time control system is a-chieved via backstepping .The proposed controller can guarantee the good tracking performance and the tracking error converge to a small neighborhood of the origin .Simulation results illustrate the effectiveness of the proposed control scheme .
