【摘要】 针对传统的三相永磁同步电机存在的矢量控制方式启动电流和超调量过大及抗干扰性不强等问题，本文设计了一种基于自抗扰控制器的三相永磁同步电机矢量控制系统。在传统双闭环PI控制系统结构的基础上，在Matlab/Simulink软件中，分别采用PI控制器和自抗扰控制器搭建转速环三相永磁同步电机矢量控制系统模型，为了对比控制效果，将两种控制器置于相同电机参数和相同仿真条件下，通过仿真得到两种控制方法下的电机转速、电磁转矩和电流响应。仿真结果表明，基于自抗扰控制器的三相永磁同步电机矢量控制系统，控制性能更优，具有更小的超调量、更好的动态性和更强的鲁棒性。该研究为永磁同步电机的矢量控制提供了理论参考。更多还原

【Abstract】 Aiming at the problems of excessive starting current, excessive overshoot and weak anti-interference of three-phase PMSM in traditional vector control, a three-phase PMSM vector control system based on ADRC is designed in this paper. Upon the traditional double closed-loop PI control system structure, the three-phase PMSM vector control system models with PI and ADRC controller in speed loop are built in Matlab/Simulink. In order to analyse the effect of two methods, the two controllers are placed under the same motor parameters and the same simulation conditions. By simulation, the motor speed response, electromagnetic torque and current response under the two methods are obtained. The simulation results show that the three-phase PMSM vector control system based on ADRC has better control performance, smaller overshoot, better dynamics and stronger robustness. This research provides a reference for vector control of permanent magnet synchronous motor.更多还原
