ABSTRACT: Due to the special features of great inertia, pure lag
and non-linearity provided with wind turbine, coupled with complex and variable
working condition, it is difficult to achieve satisfactory control results simply
by employing traditional PID, which has the drawbacks such as adjustment
inconvenience, poor anti-interference, and large overshoot, and prolonged
adjust span. This paper puts forward one type of improved controller combining
Fuzzy Control with PID Control. With larger speed deviation, the controller emphasizes
Fuzzy Control to speed system response; with less speed deviation, the
controller emphasizes PID Control to improve control accuracy. Simulation Test
directing at the algorithm is based on the Bladed software, with the positive
result of improved dynamic and static performance of wind turbine under large
disturbance.
