摘要
提出了一种永磁同步电动机(PMSM)的逆系统线性化解耦控制方法。首先,通过非线性状态反馈获得PMSM的逆系统,将多变量、非线性、强耦合的PMSM动态解耦成转速与定子电流两个低阶的线性子系统,然后,分别设计线性控制器对转速与定子电流子系统进行闭环控制。仿真结果表明:提出的控制方案具有优良的动态和静态性能,且对负载变化具有较强鲁棒性。
A novel inverse decoupling control method of permanent magnet synchronous motor drives is proposed in this paper. First, the inverse system of PMSM is obtained by means of nonlinear state feedback. So the multivariable, nonlinear and strongly coupling PMSM is decoupled into two independent linear subsystems, the speed and stator current subsystem. Then, the two linear controllers are designed respectively to control the speed and stator current subsystem. Simulation results show that the proposed control scheme possesses excellent control performance and good robustness against load disturbance.
