摘要
设计了一种新颖的由非线性综合控制方法实现的表面式永磁同步电机调速系统.首先构造了基于扩张状态观测器(ESO)的自适应滑模速度调节器,采用ESO估计系统的部分扰动项并进行前馈补偿,参数的不确定项由新的自适应控制律估计得到;然后设计了自抗扰-无源电流调节器,简化了控制器的设计,在稳定性的基础上增强了鲁棒性和快速性.仿真结果表明,该方法对负载的自适应性、抗扰动性和鲁棒性均较强,系统具有优良的动、静态性能.
A novel surface permanent magnet synchronous motor（SPMSM） speed control system is designed by using nonlinear syncretized control method.Adaptive sliding mode speed controller is presented based on the extended state observer（ESO） which observes the part of disturbance,and then compensates it to the system.The derivative of adaptive control estimates the unknown uncertainty upper boundary.Active disturbance rejection-passivity-based current controller is proposed,which simplifies the controller＇s design,and strengthens the system＇s robustness and the rapidity in the stable foundation.The simulation results show that the advantages of adaptivity,strong robustness against parameter variations and load disturbance are achieved by using this method,and the system has a satisfactory dynamic and static performance.
