In view of asynchronous motor simulation of wind turbine systems exist many problems, making use of direct torque control system has a simple structure and control methods. Using the fuzzy control to optimize the conventional direct torque control technique, making system has a better stability and dynamic response. Using gray prediction to optimize the system state variables, making the system real-time performance and accuracy have greatly improved. The results show that the improved system in the stability, dynamic response, robustness, real-time and anti-interference ability has a marked improvement.
