摘　　要：为了改善高速永磁同步电动机的控制性能,从永磁同步电动机的非线性动态数学模型出发,应用精确线性化理论并结合滑模变结构控制方法,将转速环与电流环结合在一起设计了一体化控制器,解决了小惯量高速永磁电机电磁与机械时间常数相接近,速度与电流之间的非线性耦合问题;设计了一种能够在一个数学模型中同时辨识转速与电机参数的自适应在线辨识方法,并实现了高速电机无位置传感器运行。仿真和实验表明,该控制系统具有良好的动、静态特性和鲁棒性。To improve the dynamic performance of high-speed PMSM control system,an integrated controller for both velocity and current loops is designed based on the nonlinear dynamic math model of PMSM,which,combined with the sliding-mode variable-structure control,applies the precision linearization theory to solve the nonlinear problem of speed-current coupling caused by the close electromagnetic and mechanic time constants of high-speed PMSM.An adaptive method of online parameter identification is designed for the sensorless operation of high-speed PMSM,which,with one math model,identifies the velocity and other motor parameters at the same time.Simulative and experimental results show that the control system has better static / dynamic performance and robustness.
