摘　　要：针对传统的自抗扰控制方法存在参数整定和响应速度问题,提出了一种新型的自抗扰控制器并应用到永磁同步电机调速系统中。利用非线性干扰观测器(NDOB)取代扩张状态观测器(Extended State Observer,ESO)的综合扰动项估计,简化参数整定的同时对q轴电流进行直接补偿。在非线性状态误差反馈控制律中引入滑模控制,提高了系统的响应速度和鲁棒性,利用李雅普诺夫理论证明了稳定性。仿真结果表明了该方法的有效性。Aiming at the problem of parameter setting and the response speed of the traditional ADRC method,a novel ADRC is designed and applied to the permanent magnet synchronous motor speed control system.Nonlinear disturbance observer(NDOB) is used to replace the extended state observer(ESO) integrated disturbance estimation,which simplifies the parameter setting and makes a direct current compensation for q axis at the same time.Sliding mode control is introduced in nonlinear state error feedback control,which improves the response speed and robustness of the system,and the stability is proved by using Lyapunov theory.The simulation results show the effectiveness of the method.
