Accurate flux estimation is essential in rotor flux oriented speed sensorless induction machine control. The closed-loop of combined voltage and current (UI) mode flux observer obtains good flux estimation results in the full-speed range but has some drawbacks in the stability characteristics. This paper constructs the small signal model of the UI mode flux observer, derives the characteristic matrix to realize the stability analysis, and then calculates its stable range with the corresponding… CONTINUE READING
