摘要:

提出了一种基于二阶滑模算法的永磁同步电机速度控制方法。该方法通过编码器对电机实际的位置信号进行采样,采样的位置信号通过二阶滑模算法,计算出实际速度信号并进行速度反馈调节。研究结果表明,该方法能够提高永磁同步电机速度的稳态和动态性能,从而提高系统鲁棒性和抗干扰性。

Abstract:

A speed control method of PMSM based on second-order sliding mode algorithm was presented. According to the method, the actual position signal of motor was sampled by encoder, and the actual speed used as feedback quantity to adjust the motor speed was calculated by speed-order sliding made algorithm from the position signals. The results show that the proposed method improved the steady-state and dynamic performance of PMSM and improved the robustness and anti-interference of PMSM.

Key words: permanent magnet synchronous motor (PMSM), second-order sliding mode, speed observer, robustness
