Sensorless direct power regulation by sliding mode approach of DFIG generator based wind energy system

This paper proposes a sensorless direct power regulation based sliding mode control of a wind energy system. The aim of this paper is to evaluate the performance of the system control and tracking accuracy of rotor position estimator. Sliding mode approach introduces a direct calculation of rotor side and grid side converter voltages by the control law developed. A model-reference adaptive system (MRAS) is used to estimate the rotor position. Simulation results for the system are provided to demonstrate the effectiveness and robustness of the used control.
