Adaptive Hybrid Pitch Angle Control and MPPT for PMSG-Based Wind Power Generator Systems

Abstract

This paper presents the hybrid adaptive control approach of a Permanent Magnet Synchronous Generator (PMSG) based on a variable wind speed turbine. The suggested control technique involves controlling both the pitch angle (β) and the hybrid MPPT algorithm, whose proper operation depends on the accuracy of the (β) control. The Fractional Proportional-Integral (FPI) controller-based (PA) control technique was simulated and contrasted with the Proportional-Integral (PI) controller. With further refinements, the hybrid Maximum Power Point Tracking (MPPT) algorithm was employed for optimal power/torque. The effectiveness of the proposed scheme has been verified through simulation work using MATLAB-SIMULINK. The results demonstrated that the adaptive control strategy has good performance and reliability in terms of generation efficiency. The MPPT strategy achieves maximum energy tracking at low speeds while maintaining system stability and constant DC voltages. The FPI controller enhances the performance of the controller by reducing the rise time by 0.3%, the settling time by 2%, and the accuracy of choosing the optimal angle by an average of 3%.
