摘要 在无速度传感器的异步电动机矢量控制和直接转矩控制中,控制的精度和稳定性在很大程度上取决于电动机参数的辨识精度;同时在无速度传感器控制策略中的转速估算,同样要依赖于电动机参数。从异步电动机等效电路出发,结合电机自身特性,提出一种基于双DSP控制系统,利用变频器实现异步电动机离线参数辨识的方法。仿真和实验证明,该方法实用性很强,可以为无速度传感器的异步电机矢量控制和直接转矩控制提供高精度的参数。 In a speed sensorless vector control or direct torque control of asynchronous motors, the precision of motor parameter determined the precision of control system, also in a speed identification system. According to the equivalent circuit and the character of asynchronous motors, presented a new approach to identify parameter, with dual DSP system and convertor. The simulation and experiment indicated that this method could offer accurate parameter.
