摘　　要：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,得到所需的的坐标变换和非线性系统状态反馈,实现了永磁同步电机系统的输入输出线性化,同时也实现了系统的解耦。仿真结果表明:采用该控制方法的永磁同步电动机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。The direct feedback linearlzation （DFL） theory, which was a nonlinear control method, was employed to control PMSM in this paper. The appropriate coordinate transformation and nonlinear state feedback were obtained by Lie derivatives for output variable, with which the input - output of PMSM system was linearized. Furthermore, the completely dynamic decoupling was realized. The simulation results showed that the permanent magnet synchronous motor servo system with the method proposed in the paper not only has better position tracking performance, but also efficiently reduced the effect of torque change on position tracking.
