摘要：This paper presents modeling and nonlinear control of a grid connected wind energy conversion system based on a wind turbine using a permanent magnet synchronous generator (PMSG). The objective of the control is: assuring a satisfactory power factor correction (PFC) with respect to the power supply net. First, a model of the whole controlled system is developed in the Park's coordinates. Thereafter control strategies PFC is used to inject power into a grid while keeping a very good power factor. A nonlinear controller is synthesized using the backstepping design technique. A formal analysis based on Lyapunov stability is developed to describe the control system performances. The results of various simulations of all the chain of conversion, carried out under MATLAB/Simulink software, made it possible to evaluate the performances of the proposed system.
