摘要在永磁同步电动机双闭环速度控制系统中,提出了一种新型永磁同步电动机变结构自抗扰控制速度控制方案。在速度环设计了二阶变结构自抗扰控制器,在保持典型自抗扰控制器特点的同时,系统的自抗扰参数得以平滑的过渡。经过仿真和实验验证,改进的变结构自抗扰速度控制系统具有响应速度快、超调小和稳态误差小等优点,对转动惯量、负载及系统内部参数变化具有很强的抗扰动能力,提高了永磁同步电动机变频调速系统的动静态性能和鲁棒性。

Abstract：In the permanent magnet synchronous motor dual closed loop speed control system, a new variable structure PMSM ADRC speed control scheme is presented. Two-order variable structure active-disturbance rejection controller(VS-ADRC) of speed loop is designed, which not only maintains the typical characteristics of ADRC, but also makes the system of ADRC parameters can be transit smoothly. Simulation and experimental results show that the improved VS-ADRC speed control system with fast response, small overshoot, steady state error, etc, which makes system has a strong anti-disturbance ability improved permanent magnet synchronous motor speed regulation system dynamic and static performance and robustness to the variation of rotational inertia, load and internal variation of parameters.

Key words： Permanent magnet synchronous motor speed loop variable structure control active-disturbance rejection controller
