Based on the theoretical analysis of mathematical model for induction motor,a sensorless control system for induction motor with slide mode variable structure is designed.And a simulation platform of sensorless control system is established based on Matlab/Simulink for induction motor with slide mode variable structure.In the system controlled by rotational speed and double closed-loop,the slide mode algorithm is used for speed controller and the model reference adaptive system（MRAS） is applied in estimating the induction motor speed.Simulation results show that this method behaves robustly and offers a basis for designing and debugging motor control system.
