This paper presents a sliding mode controller (SMC) to directly control the active and reactive powers of a doubly fed induction

generator (DFIG) for wind turbines. Sliding-mode control (SMC) and space-vector modulation (SVM) are combined to ensure high-

performance operation. SMC scheme is designed to provide robust and fast power controls without frame transformation and

current controller used in the conventional FOC drive. Simulation results and experimental results demonstrate that proposed

methods preserve the effectiveness and robustness during variations of active and reactive power.
