【摘要】 针对永磁同步电机(PMSM)在传统无传感器控制策略下，存在超调严重、抖振明显，易受扰动影响的现象，提出了一种基于二阶自抗扰控制(ADRC)和龙伯格观测器的PMSM无差拍预测电流控制(DPCC)策略。速度环采用改进的二阶ADRC,并采用超螺旋算法(STA)和模糊算法对控制器进行优化。电流环采用DPCC策略替代传统PI控制。观测器采用龙伯格观测器，加入状态反馈误差的微分项并结合滑模控制进行优化。并基于StarSim实时仿真平台，搭建硬件在环(HIL)和快速控制原型(RCP)实验平台验证该策略的有效性和可行性。仿真实验结果表明，该新型控制策略可以有效地抑制系统的超调和抖振，提升转子位置的估算精度，同时提高系统的响应速度、抗扰动性和鲁棒性。更多还原

【Abstract】 Aiming at the phenomenon that permanent magnet synchronous motor(PMSM) suffers from serious overshoot, obvious chattering, and is easy to be affected by disturbance, under the traditional sensorless control strategy, a control strategy based on second-order active disturbance rejection control(ADRC),Luenberger observer and deadbeat predictive current control(DPCC)for PMSM is proposed.The improved second-order ADRC is used in the speed loop and the super-twisting algorithm(STA)and fuzzy algorithm are used to optimize the controller.The current loop adopts DPCC strategy to replace traditional PI control.The Luenberger observer is adopted, which is optimized by adding a differential term of state feedback error and combining with sliding mode control.Hardware in the loop(HIL)and rapid control prototype(RCP)experimental platforms are built on the StarSim real-time simulation platform to verify the effectiveness and feasibility of this strategy.The simulation and experimental results show that the new control strategy can effectively suppress the overshoot and chattering, improve the precision of rotor position estimation, and improve the response speed, anti-disturbance capability and robustness of the system.更多还原
