Research on Permanent Magnet Synchronous Motor Speed Control System Based on Active Disturbance Rejection Control

永磁同步电机(Permanent Magnetic Synchronous Motor, PMSM)因结构简单、尺寸灵活多样、效率高、可靠性强、易于控制等优点,已在航空航天、武器随动系统、船舶动力定位等领域广泛应用。自抗扰控制作为一种新型的非线性控制技术,可以有效克服PID控制在复杂、高效控制领域的缺点。设计一种自抗扰控制器取代速度、电流环的PI控制器,在MATLAB/Simulink中搭建系统模型。仿真结果表明,运用自抗扰控制可以有效解决超调与抗扰问题,提高控制性能。

Permanent Magnetic Synchronous Motor (PMSM) has been widely used in aerospace, weapon follow-up systems, ship dynamic positioning and other fields due to its simple structure, flexible size, high efficiency, high reliability, easy to control and other advantages. As a new type of nonlinear control technology, active disturbance rejection control can effectively overcome the shortcomings of PID control in the field of complex and efficient control. Design a PI controller that replaces the speed and current loop with an active disturbance controller, and build a system model in MATLAB/Simulink. The simulation results show that the active disturbance rejection control can effectively solve the overshoot and anti-interference problems and improve the control performance.
