[0055] Such as figure 1 As shown, the system input is the blade pitch angle β and the generator torque T g , the system output is the generator speed Ω; V is the wind speed, λ is the blade tip speed ratio; R is the radius of the wind rotor, T a ,F a Torque and thrust generated by capturing wind energy for the wind rotor, f(λ,β,V 2 ) is a nonlinear function. According to the LPV method, it is necessary to find a suitable scheduling parameter p to characterize the working state of the system and divide the stable working point of the system. For wind turbines, the external input wind speed V is expressed as two parts in In order to represent the effective wind speed of the wind turbine operating state (hereinafter referred to as the effective wind speed), v represents the interference superposition on the effective wind speed, and The different values of determine the different operating points of the system, so the effective wind speed is selected as a scheduling p...
