摘要：在永磁同步电机（PMSM）调速系统中，提出速度环改进型自抗扰控制策略。通过将线性自抗扰控制器(LADRC)中扩张状态观测器降阶设计出降阶自抗扰控制器(rLADRC)，相对于LADRC，rLADRC的状态观测器只需观测综合扰动，观测器的简化提高了观测速度和精度，而观测器中对于直接测量的滤波处理有效的抑制了噪声信号，最后对rLADRC进行了稳定性分析并通过仿真和实验验证了降阶自抗扰控制策略在PMSM调速系统中的可行性与正确性。

Abstract: In the Permanent Magnet Synchronous Motor(PMSM) speed regulation system,an improved active disturbance rejection Control strategy was proposed .The Linear Active Disturbance Rejection Control (LADRC) in the reduced order extended state observer design to reduced order Active Disturbance Rejection Control (rLADRC).Compared with LADRC, rLADRC state observer comprehensive disturbance observation,the simplified structure improves the observation speed and observer for direct measurement of filter processing to suppress the noise signals effectively.Finally to analyze the stability of rLADRC,simulation and experiment results show that is feasibility and correct of rLADRC strategy in the PMSM speed control system.
Key words: permanent magnet synchronous motor; speed regulation system; reduced order active disturbance rejection control
