PID control in adjustable-pitch wind turbine system based on fuzzy control

PID controller is widely used in different kinds of industry circumstance. Because of the difficulty for modeling the industry plants and the frequent change of the parameters of plants, it often could not be gotten optimal control effects by using common PID controllers. So it is significant to find the tuning methods which are simple, practical and have good performance. A fuzzy tuning algorithm is gives and the algorithm simulated by Matlab. The results show that the method is practical and effective.
