An advanced control applied to PMSG wind energy conversion system implemented under graphical user interface

This work presents the study of a wind energy conversion system based on permanent magnet synchronous generator controlled by an advanced frequency techniques applied to two levels of control system: turbine speed control which allows to extract the maximum wind power based on the control of the PMSG electromagnetic torque and V-dc (DC-link voltage) control based on vector control to ensure a constant tension under the variations in the wind speed. The robust H-& INFIN; control efficacy is validated in comparison with the MPPT controller based on perturb and observe algorithm and conventional regulator PID. The computer simulation results obtained by a realized graphical user interface (GUI) using robust H-& INFIN; controller with robustness test (variations in electrical and mechanical parameters) show considerable improvements in dynamics performances, robustness stability and good adaptation of the robust H-& INFIN; parameters under uncertain constraints.
