A Novel Nonsingular Terminal Sliding Mode Control-Based Double Interval Type-2 Fuzzy Systems: Real-Time Implementation

Extensive use of wind turbine (WT) systems brings remarkable challenges to the stability and safety power systems. Due difficulty complexity modeling such large plants, model-independent strategies are preferred for control WT plants which eliminates need model identification. This current work proposes a novel methodology in rotor side converter (RSC) part ameliorate low voltage ride through (LVRT) ability especially doubly-fed induction generator (DFIG) WT. A nonsingular terminal sliding mode (MINTSMC) was developed based on principle ultra-local pattern. In suggested controller, MINTSMC scheme designed stabilize RSC DFIG, sliding-mode supervisor adopted determine unknown dynamics proposed system. An auxiliary dual input interval type 2 fuzzy logic (DIT2-FLC) established structure remove estimation error observer. Real-time examinations have been carried out using Real-Time Model Loop (RT-MiL) validating applicability real-time platform. To evaluate usefulness supremacy DIT2-FLC, outcomes compared with regulated conventional PI controller controller.
