Optimal Control of Variable Speed Wind Turbines Using Adaptive Fuzzy Controller

Vidya G H, Ashok Kusagur

Abstract: In order to maximize energy capturing in wind turbines, the wind turbine generator needs to tune the speed of the wind turbine according to the wind. Conventional controllers have low efficiency to obtain the better dynamic quality and robustness. In this paper, an adaptive fuzzy controller on the variable speed wind turbines was proposed and it was compared with PID and Fuzzy controllers. The use of adaptive fuzzy controller causes the system does not have any steady-state error at all moments of time, the response rate is better than PID and fuzzy controller as obtained from the simulated results in Matlab/Simulink
