摘要
分析了永磁同步电机的直接转矩控制系统中定子电阻变化对系统性能的影响,利用真正定子电流与参考定子电流之差来跟踪定子电阻的变化,实现定子电阻的在线估计,仿真结果证明了此估计方法可准确估计定子电阻,改善控制系统性能。
The effect of stator resistance variation on direct torque control（DTC） of permanent magnet synchronous motor（PMSM） is analyzed. By means of comparing the actual current and the reference current, the change of stator resistance can be tracked and the stator resistance can be on-line estimated. Simulation results demonstrate the method could accurately estimate the stator resistance and improve the DTC performance.
