In this paper, the design of sensorless induction motor speed controller using the concept of multirate output feedback discrete-time sliding mode control technique is proposed. The nonlinear model of the motor is linearized at its operating point and the multirate output feedback discrete time sliding mode control using output samples is designed and the same is applied to nonlinear model of the motor at its operating (equilibrium) point. This method docs not require the complete states of the system for feedback and is easily implementable.
