Abstract：The application of the passivity-based control (PBC) theory to the VSCF wind power generator control is a novel method. In this paper, the doubly fed generator is considered as a non-linear system using energy concept and the main purpose is to design a passivity-based control algorithm that combines the three aspects of unity power factor in the stator side, the maximum wind energy capture and system stability. The asymptotic tracking of currents and rotor speed are obtained by the harmonious operation between current inner-loop and rotor outer-loop. The designed controller achieves maximum wind energy capture in such a way that the fast dynamic response and good accuracy, meanwhile, it has strong robustness under generator parameters and load disturbance compared to conventional vector control. The reasonability and validity is testified by the simulation results based on Matlab.
