基于分时法的无速度传感器感应电机驱动定转子电阻在线解耦辨识

The paper addresses the method for stator and rotor resistance identification in speed sensorless induction motor drives. The instability problem caused by pure integration of the voltage model (VM) of rotor flux is handled by introducing correction terms in the VM. It is, however, shown that the third-order persistent excitation (PE) condition for simultaneous identification of stator, rotor resi...
