Commandes non linéaires robustes de systèmes éoliens

Abstract : This work deals the nonlinear control of wind turbine structures. The first objective is the design of control laws of a standard wind turbine with variable speed-variable pitch angle. The proposed control strategies allow controlling the wind turbine indifferent operating areas (optimization and powerlimitation).The second objective consists in controlling a new structure of twin wind turbines. The originality of this structure lies in the fact that it can rotate face the wind without using a dedicated actuator, thanks to the free rotation of the arm carrying the wind turbines. Two control architectures are proposed in order to ensure the structure face the wind : pitch angles differential and the produced power difference. Given that the environment is uncertain (windvariations, modeling errors, noise), robust nonlinear control laws are proposed for a multiple objectives. The efficiency of the control strategies have been carried out according to several scenarios.
