چکیده
|
The maximum power point tracking problem of variable-speed wind turbine systems is studied in this paper. the wind conversion systems contain both mechanical part and electromagnetic part,which means the systems have time scale property. the wind turbine systems are modeled using singular perturbation methodology. a linear parameter varying (lpv) model is developed to approximate the nonlinear singularly perturbed model. then stability and robust properties of the open-loop linear singularly perturbed system are analyzed using linear matrix inequalities (lmis). an algorithm of designing a stabilizing state-feedback controller is proposed which can guarantee the robust property of the closed-loop system. two numerical examples are provided to demonstrate the effectiveness of the control scheme proposed. � 2016 yan zhang et al.
