| 摘 要： | 针对传统永磁同步电机滑模控制存在的抖振以及系统抗扰动鲁棒性差问题,提出一种基于扩张状态观测器的永磁同步电机自抗扰无源控制方法。转速外环设计自适应滑模控制器,采用扩张状态观测器对系统干扰项进行观测,用其进行前馈补偿。电流内环将无源控制与自抗扰控制相融合,得到d-q旋转坐标系下的电压给定。新型控制方法可有效抑制系统抖振,增强系统鲁棒性。试验结果验证了所提控制方法的有效性和实用性。

| Abstract: | The traditional sliding mode control (SMC) of permanent magnet synchronous motor (PMSM) had buffeting problem, and its robustness to perturbation was poor. In view of this problem, a method of active disturbances rejection control (ADRC) and passive-based control (PBC) for PMSM based on extended state observer (ESO) was proposed. In out speed loop, a adaptive SMC was designed, and the system disturbances were observed for feedforward compensation by using the ESO. In internal current loop, PBC was combined with ADRC to obtain the voltage reference in the dqrotating coordinate system. The new control method could effectively suppress the system buffeting and enhance the robustness of the system. The experimental results verified the effectiveness and practicability of the proposed method. |
