Abstract :
In consideration of the intrinsic properties such as nonlinearity, uncertainties and randomness of the Wind Energy Conversion System (WECS) based on Permanent Magnet Synchronous Generator (PMSG), the Model Predictive Control (MPC) method is utilized to realize the power tracking control of the system. A simplified second-order linear model by the pre-feedback and the forward difference are adopted to improve the feasibility of the MPC algorithm. In addition, a fast computing method, the Continuation/GMRES (C/GMRES) method, is employed to obtain the control sequence. Simulation results verify the effectiveness of the designed model predictive controller, in term of the power tracking ability of the system under the varying load demand and parameters perturbation.
