Abstract

This paper proposes a deadbeat control method for the current control loop as a replacement for the conventional proportional–integral (PI) controller in a wind turbine system using a permanent magnet synchronous generator (PMSG). The main objective is to ensure optimal rotor speed tracking, as determined by the Maximum Power Point Tracking (MPPT) algorithm, even under continuously varying wind conditions. The deadbeat current controller takes advantage of the computational capabilities of modern DSPs or FPGAs. Designing the controller in the discrete domain helps avoid errors caused by approximating the model from continuous to discrete form, thereby improving control performance and reducing torque ripple. The effectiveness of the proposed method is verified through simulations in MATLAB/Simulink, demonstrating superior performance compared to the conventional PI controller. These results confirm the feasibility of the proposed strategy in enhancing the efficiency of the wind energy conversion system.
