摘　　要：介绍了一种内埋式永磁(IPM)同步电机的在线参数估计方法。该方法基于带有饱和的最大转矩/安培轨迹,提高了电机驱动的效率。同时,消除了参数的交叉耦合,使参数估计具有鲁棒性。模型与闭环观测器相结合改善了参数估计。仿真和实验结果证实了方法的可行性。An on - line parameter estimation method of IPM synchronous machine based on maximum torque - per - ampere trajectory including the effect of magnetic saturation to improve efficiency of machine drives is presented in this paper. Crosscoupled parameters can be eliminated for the robustness of pa- rameter estimation. Moreover, parameter estimation is improved by combining the model with a closed loop observer. Simulation and experimental results confirm the effectiveness of the proposed solution.
