Abstract
Concerning the external disturbance, nonlinear operation conditions and parametric uncertainties of wind conversion system based permanent magnet synchronous generator (PMSG), in this paper we propose a passivity-based control (PBC) combined with fuzzy logic controller for dynamic performance improvement. The studied renewable system is constituted by a wind turbine based PMSG connected to the electrical grid through PWM converter. The PBC is applied to the generator-side when a conventional PI control is applied to the grid-side. Numerical investigation under MATLAB/Simulink environment, demonstrate that the proposed control solution provides efficiency, effectiveness of the developed strategy.
