摘　　要：在永磁同步电机伺服控制系统中,精确的参数辨识对于电机控制与运行状态监视具有重要意义。基于永磁同步电机在d-q轴的动态方程,在矢量控制的基础上,运用带遗忘因子的多新息最小二乘法,精确地完成了电机的在线多参数辨识。辨识过程仅需采集电机输出的电压、电流和转速信号,简单方便。仿真结果表明该方法具有较好的收敛性与鲁棒性。In the permanent magnet synchronous motor servo system, accurate parameter identification is very important to motor control and operation state monitoring. Based on the dynamical equations of d-q axis currents, the multiple innova- tion least squares method was used to do real time multi-parameter identification accurately on vector control platform. The stator voltage, stator current and rotor speed were collected in the process. The simulation results show that this method is of better convergence and robustness.
