摘　　要：经典PI调节的永磁同步电动机转速控制,存在快速性与超调量之间的矛盾。将自抗扰控制技术应用于永磁同步电动机转速控制中,设计跟踪微分器对输入安排过渡过程,使系统有良好的转速适应性;扩张状态观测器通过对综合扰动项的观测和实时补偿,增强了系统的鲁棒性。仿真实验结果表明,基于ADRC的PMSM转速调节系统,可实现对输入信号的快速无超调跟踪。In the permanent magnet synchronous motor （PMSM） speed control system, the dynamic response speed and overshoot is contradictory in classical PI regulator. ADRC was introduced into PMSM speed control. Tracking differentiator was adopted to set up a transition for the input, allowing the system work with good speed adaptability, and the extended state observer was used to enhance the robustness of the system by observing and real-time compensating general disturbance. Simulation results show that the speed control system based on PMSM using ADRC can follow the reference speed quickly without overshoot.
