摘要:永磁同步电机是一种强耦合、时变系统,对外界扰动及内部参数变化较为敏感。为了优化速度控制性能,本文采用了一种基于滑模控制和扰动补偿的速度控制技术,这种方法在有效降低传统滑模控制带来的抖振同时能加快响应速度。实验结果与传统滑模控制进行比较,证明了该方法的有效性。

In order to optimize speed control performance, This paper adopted a speed control theory based on sliding mode control and disturbance compensation. The method can dynamically adapt to the variations of the controlled system, which reduce chattering trough controlling input. Comparing with tradition sliding mode control, the experimental results verified the effectiveness of the proposed method.
