Abstract An improved integral sliding mode observer in this paper is proposed for speed identification in induction motor, compared with traditional sliding mode observer, the steady-state error and buffeting of the control system are reduced, and the integral saturation is effectively suppressed. Based on the phase-locked loop decoding technique, the rotor position angle is calculated. The system has a good performance in speed tracking and has a satisfied accuracy of identified speed in full speed range. Finally, the correctness of the speed identification strategy proposed in this paper is verified by simulation and experimental study.
