FSMC for PWM rotor side converter in DFIG-based wind turbine system

Abstract

The doubly-fed induction generators (DFIGs) are highly complex systems with nonlinearity and uncertainty. Therefore, employing robust intelligent control is required to improve the system performance. This paper takes advantage of combining the sliding mode control (SMC) and fuzzy control. The proposed controller, known as fuzzy sliding mode control (FSMC), can reduce the fluctuation produced by the pulse with a modulation converter and accelerate the trajectory to the sliding surface. The closed-loop system stability is also guaranteed in this work. The results simulation shows good performance and robustness of the proposed controller.
