摘要:In this paper, a problem of mechanical modeling and robustly stabilization of awind system formed by a turbine, a driving shaft and an induction machine, is considered.To overcome the complexity and the non-linearity of the system, the model of the windgenerator is approximated by a Takagi-Sugeno fuzzy model. Hence, to stabilize the obtainedfuzzy model, two command approaches were developed. They are the fuzzy controller usingthe parallel distributed compensation (PDC) and the 𝐻∞ controller based-fuzzy observer.Numerical optimization problems using linear matrix inequality (LMI) and convextechniques are used to analyze the stability of the wind generator. Finally, simulationexamples illustrating the control performance and dynamic behavior of the wind generatorunder various command approaches are presented.
