Abstract

In this paper a new strategy for sensorless control of induction motors using adaptive sliding observer is presented. Variable structure and nonlinear controls such as sliding mode are used in most application with high robustness and reliability. In the proposed observer, rotor flux component is obtained using some electric equations in the stationary reference frame and Lyaponov function is used to estimate the motor speed. Simulation results demonstrated the proposed vector control for induction motor using adaptive sliding observer.
