| 摘 要： | 为实现永磁同步电机的高性能控制,提出一种复合控制策略。在永磁同步电机矢量控制基础上,设计反步控制器用于电流环控制,得到同步旋转坐标系下定子电压,并能保证系统全局稳定。设计结构优化的线性自抗扰控制器用于速度环控制,提高系统抗干扰能力。采用二阶环节平滑速度指令,实现转速无超调。仿真结果表明该控制策略较传统PI控制具有转速适应范围广、无超调、抗扰动性能强等优点。

| Abstract: | A compound control strategy for PMSM is proposed in order to achieve high performance control. On the basis of vector control system for PMSM, a backstepping controller is designed for electric current loop control to obtain the stator voltage in synchronous rotating coordinate and to ensure the stability of the system. A linear structure-optimized active disturbance rejection controller is designed for speed loop control to improve the anti-disturbance ability of the system. A two-order link is adopted to achieve smooth speed signal and perfect non-overshooting speed. Simulation results show that, compared with traditional PI control, the compound control strategy has wider adaptive range of speed, non-overshoot, stronger anti-disturbance ability, and so on. |
