Robust control of rotation speed control of wind turbine based on closed-loop gain shaping

A robust controller is designed based on closed-loop gain shaping robust control theory for wind power generation system with the random of wind speed, the disturbance of wind torque, observation noise as well as the unmodelled uncertainty in high frequency. And the rotation speed control of generator by controlling the electromagnetism torque is realized. The results of the simulation show that it can fast track the instructions produced by MPPT and achieve the high efficiency transition from wind energy to electricity energy even if under the condition of strong wind torque, the observation noise perturbation and the large scale fluctuation of moment of inertia of generator, read papers conveniently.
