Robust fuzzy PID controller for wind turbines

PID and fuzzy PID controller are used for the wind turbine with the nonlinear mathematical model. PID control has simple principle and its parameters setting are rather easy. Fuzzy PID controller combines with the reasoning goals/constraints on robustness (robust fuzzy PID controller), which can effectively improve the robustness. MATLAB software is used for simulations, and the results display that the robust fuzzy PID controller has better performances than the PID controller when errors exist, especially robustness performance.
