%X The conventional wind turbine controller can not realize the global range control because of its local linearization at specific operating point. It neither provides the rejection of internal and external disturbances. In our approach, the nonlinear model of the wind turbine is converted to a global linear model by using the differential geometry method. For this global linear model, a linear H-infinity variable pitch controller is designed for the existing wind power system. Simulations of the control system are carried out for 12--24 m/s step wind, 12--22 m/s suddenly change wind, 18--20 m/s random wind, and 10% reduction of wind turbine rotary inertia. Results show that the wind turbine speed and the output power are maintained at constant values as desired, showing desirable performances and robustness of the control.
