| 摘 要： | 在分析永磁同步电机(PMSM)系统模型的基础上,提出了一种基于扩张状态观测器(ESO)及非线性跟踪微分器(NTD)的PMSM无机械传感器位置控制系统。控制系统通过基于ESO及NTD的观测器实时观测出电机转子位置及转速,在此基础上实现PMSM无机械传感器位置控制。仿真和实验结果表明该系统结构简单,控制快速、准确、无超调,对于外界干扰具有较强的鲁棒性。

| Abstract: | This paper proposed a PMSM sensor-less position control system based on an ESO and a NTD,to improve position control in servo systems of PMSM.The rotor position and speed will be estimated by an ESO and a NTD,and the accurate closed-loop control will be achieved on this basis.Simulation and experimental results show that the control system is simple,and will give fast,accurate position control results. |
