This paper presents a new control method to track the maximum power point for a Wind Energy Conversion System (WECS). This WECS is based on a permanent magnet synchronous generator (PMSG) fed by a matrix converter. Since the mechanical power generated by the wind turbine is a function of its shaft speed at a given wind velocity, the proposed controller provides the desired voltage at the output of the matrix converter so as to control the generator speed. This controller is based on the nonlinear adaptive backstepping approach which is well suited for this system. This method is able to effectively accommodate the effects of system uncertainties. Theoretical analysis and simulation results verify the feasibility and performance of the proposed approach.
