摘要: 研究了一种基于不确定干扰估计器( UDE) 的永磁同步电机控制策略。 根据 UDE 控制理论,设计 UDE控制器代替双闭环矢量控制中的传统 PI 控制器,增强了电机系统对外部干扰和内部参数变化的抗扰能力,并通过仿真与实验对控制策略进行验证。 结果表明,针对突变干扰以及参数不确定性等影响因素,UDE 控制器相较于 PI 控制器具有更好的鲁棒性。

Abstract: A control strategy for permanent magnet synchronous motor based on uncertainty and disturbance estimator ( UDE) was studied. According to the UDE control theory, the UDE controller was designed to replace the traditional PI controller in the double closed-loop vector control, which enhanced the anti-disturbance ability of the motor system to external disturbances and internal parameter changes, and the control strategy was verified by simulation and experiment.The results indicate that the UDE controller has better robustness compared to the PI controller in response to factors such as sudden disturbance and parameter uncertainty.

Key words: permanent magnet synchronous motor ( PMSM ), motor drive control, uncertainty and disturbance estimator( UDE), anti-interference performance
