摘要

Direct feedback linearization control was applied to permanent magnet synchronous generator (PMSG) wind energy conversion system (WECS),which was to reduce the cost of wind energy conversion system and improve its performance.The PMSG-based wind energy conversion system was constructed with mathematical models of aerodynamics subsystem,drive train subsystem and simplified electromagnetic subsystem.With feedback linearization control theory based on differential geometry,the coordinated transformation and nonlinear state feedback were obtained and PMSG wind energy conversion system was linearized.With MATLAB/Simulink platform,the model and control strategy was established and the simulation result shows this control system with feasible speed tracking performance,which can effectively implement maximum energy capture.
