Single-phase sinusoidal inverter based on fuzzy PID control for small wind power system

A single-phase sinusoidal inverter with high-frequency link for small wind power system is proposed to improve reliability and energy conversion efficiency in this paper. A fuzzy self-tuning PID controller is designed for the proposed inverter. A model is set up and simulated in MATLAB. The simulation result shows that the single-phase sinusoidal inverter has high steady-state accuracy and dynamic characteristics with the use of proposed fuzzy PID controller. Therefore, the control method suggested in this paper can ensures the inverter meets the need of small wind power system.
