基于并联RSO优化自抗扰的PMSM速度控制

PMSM Speed Control Based on Active Disturbance Rejection Control Optimized by Parallel Reduced-order State Observer

为提高永磁同步电机调速系统的速度精度及抗干扰能力,提出一种并联降阶状态观测器优化线性自抗扰控制的方法。对传统线性扩张状态观测器进行改进,设计了降阶状态观测器。为了提升控制器在有限带宽内的抗扰动能力,设计并联型的降阶状态观测器。仿真结果表明,控制系统的速度精度和鲁棒性得到明显的提升。

To improve the speed accuracy of PMSM speed regulation system and the anti-disturbance ability,a control method based on linear active disturbance rejection control optimized by parallel reduced-order state observer is proposed.The traditional linear extended state observer is improved and the reduced-order state observer is designed.In order to improve the anti-disturbance ability of the controller within the limited bandwidth,a parallel reduced-order state observer is designed.Simulation results demonstrate that the speed accuracy and robustness of the control system are further upgraded.
