| 摘 要： | 永磁同步电动机(PMSM)是一个复杂耦合的非线性系统,本文应用一种非线性控制方法--直接反馈线性化理论,通过对输出变量进行李微分,得到所需的坐标变换和非线性系统状态反馈,实现PMSM系统的输入输出线性化,同时也实现了系统的解耦.Matlab仿真结果表明,该控制方法对PMSM伺服系统具有良好的位置跟踪性能,而且能够有效降低转矩变化对位置跟踪性能的影响.

| Abstract: | Permanent magnet synchronous motor(PMSM) is a nonlinear system with significant coupling.By using the direct feedback linearization theory which is a nonlinear control method,the appropriate coordinate transformation and nonlinear state feedback are obtained through Lie deriving the output variable.The input-output linearization of PMSM system and the completely dynamic decoupling are realized.The Matlab simulation results show that permanent magnet synchronous motor servo system has good position tracking performance,and the effect of torque change to position tracking is efficiently reduced. |
