In this paper, an enhanced Integral Sliding Mode Control (ISMC) for mechanical speed of Induction Motor (IM) is presented and experimentally validated. The design the proposed controller has been done in d-q synchronous reference frame indirect Field Oriented (FOC). Global asymptotic tracking presence model uncertainties load torque variations guaranteed by using ISMC surface. Moreover, provide...

This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...
