The optimal torque (OT) method, which is preferred for its simplicity, is widely employed in maximum power point tracking (MPPT) control strategies for wind energy capture in wind turbine generators (WTGs). Based on the OT method, the decreased torque gain (DTG) method is developed to improve turbine acceleration through a reduction of the torque gain coefficient. However, the DTG method does not fully align with the acceleration performance required by wind turbines, which subsequently limits improvements in wind energy capture efficiency. To address these concerns, a novel MPPT control strategy is proposed, which introduces redefined torque curve and torque command conceptualized based on a higher-order function relative to rotor speed. Additionally, an adaptive algorithm for the periodic update of the torque command is suggested to better accommodate the variability of turbulent wind speeds, thus aiming to improve the wind energy capture efficiency. The effectiveness of the proposed MPPT control strategy is substantiated through the wind turbine simulator (WTS)-based experiments.
