Parameter Identification for Induction Motor on the Structure of Three-Level Inverter Vector Control

从异步电动机的状态方程出发,在静态条件下采用特殊信号激励方式,对三电平逆变器矢量控制结构下的异步电动机进行参数辨识。仿真和实验结果验证了方法的准确性。

Base on equations of state, the self-commissioning of induction motor is implemented on the structure of three-level inverter vector control at the standstill by especial signal prompting. The validity of the proposed method is demonstrated by the simulation and experimental results.
