| 摘 要： | 基于三相永磁同步电动机（PMSM）在两相同步旋转坐标系中的数学模型，得到PMSM的欧拉-拉格朗日（EL）模型。利用EL模型研究了PMSM的无源性和耗散性。基于PMSM的无源性，提出了一种新的基于误差状态变量的阻尼注入方法，利用该方法设计了系统无源控制器。该无源控制器可加速系统的响应，使系统具有良好的动、静性能。建立了PMSM的MATLAB／Simulink环境下无源控制系统仿真模型，仿真结果表明提出的利用误差状态变量的阻尼注入方法设计无源控制器是可行的。

| Abstract: | Based on the mathematical model of three-phase permanent magnet synchronous motor （PMSM） in the two-phase synchronous rotating coordinate system, the Euler-Lagrange （EL） model of PMSM is obtained. The passivity and dissipation of PMSM has been studied by making use of EL model. A new damping injection method based on the error state variables is proposed on the ground of the passivity of PMSM. The system passive controller is designed with the new method. The passive controller can speed up the system response to achieve good dynamic and static performance. The system simulation model of PMSM is established under MATLAB/Simulink environment. The simulation results show the proposed passive controller is feasible. |
