Abstract :
In this work we are interested in modeling and control of a wind system formed by a turbine, a driving shaft and a double fed induction machine. We are used the multi model method to overcome the non linearity of the system. Hence two techniques of command were developed. They are the feedback command state and the standard command using the quadratic functions of Lyapunov and the LMI approach. The simulation shows the control performances and dynamic behavior of the wind system. The standard command permits the stability of the system and attenuation of the external disturbances caused by the variation of the wind speed.
