This paper presents an enhanced Super Twisting Sliding Mode Control (STSMC) technique for wind turbine systems by integrating a fuzzy logic controller (FLC) to dynamically regulate the STSMC gain. The FLC adjusts the gain based on the error signal from the STSMC, leading to improved adaptability and system performance. This approach enhances responsiveness to sudden changes and disturbances, resulting in better transient response and reduced steady-state error. Simulation results confirm that the Fuzzy Super Twisting Sliding Mode Control (FSTSMC) outperforms the standard STSMC, offering automatic gain adjustment and eliminating the need for manual tuning. The proposed method significantly improves system performance in dynamic conditions.
