一种简化的PMSM自抗扰控制技术分析

Analysis of PMSM Based on Simplified Auto-disturbance Rejection Controller Technical

针对于永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)的直接转矩调速系统相对复杂、难以控制的特点,加之引入传统自抗扰控制器后系统鲁棒性差。研究了一种简化的自抗扰控制器(Auto-disturbance rejection controller,ADRC),该控制策略因减少了整定参数而提高了系统的误差估计补偿、抗干扰能力以及响应速度。该系统的转矩和磁链脉动明显降低。通过仿真和实验分析,对比空载和带载的不同情况,结果表明,基于自抗扰控制的PMSM控制系统具有良好的动态性能,验证了所述控制策略的和有效性。

It is relatively complicated and dltlicult to control in all-Olgltat fuzzy tur^t~t totqu~ ~unuut ~y^tu l~,~ the permanent magnet synchronous motor, and the robustness is poor combining with the traditional ADRC controller parameter. This paper studies auto-disturbance rejection controller （ADRC）, which reduces the setting parameters and improves the system error compensation, anti-interference ability and the response speed. The torque and flux pulsation is obviously reduced in the system. Through the simulation analysis, comparison of the different situations of no-load and load, the results show that the immunity control has good control performance, verifying the effectiveness of the proposed control strategy.
