摘　　要：由于负载突变或者受到一定程度干扰时会造成永磁同步电动机鲁棒性减弱,抗干扰能力下降等问题,文章提出基于不确定干扰估计器(uncertainty disturbance estimator,UDE)的永磁同步电动机速度控制策略。与传统PI控制策略不同,该文所提出的控制策略对内部参数变化和外部扭矩干扰具有鲁棒性,能够确保对于不同类型的扰动具有抗干扰能力,同时可以消除控制器参数的整定环节。通过Matlab/Simulink仿真建立永磁同步电机控制模型,施加不同类型的干扰,验证基于不确定干扰估计器的永磁同步电动机驱动速度控制方法的跟踪能力和抗干扰能力。Because the permanent magnet synchronous motor’s robustness and anti-interference ability will be weakened when the load suddenly changes or is disturbed to some extent,this paper proposes a speed control strategy of permanent magnet synchronous motor based on uncertainty disturbance estimator(UDE).Different from the traditional PI control strategy,the control strategy proposed in this paper is robust to internal parameter changes and external torque disturbances,which can ensure the anti-interference ability for different types of disturbances,and can eliminate the tuning link of controller parameters.The control model of PMSM is established by Matlab/Simulink simulation,and different kinds of interference are applied to verify the tracking ability and anti-interference ability of PMSM drive speed control method based on uncertain interference estimator.
