Summary:We have proposed a current observer-based induction motor speed sensorless vector control system which is composed in a rotating reference frame. The characteristic improvement of this system is discussed by taking into account iron loss, stator resistance identification, current low-pass filter and speed estimation low-pass filter. The stability of the system has been investigated by the trajectories of poles and zeros. The effectiveness of the proposed system has been investigated by digital simulation and experimentation.
