Abstract:  
This paper presents a complete nonlinear model for a wind turbine system with a variable speed cage machine generator, firstly. Then a primary controller which is named “reference signal generator” will be designed to lead system to optimum operating condition at various wind speeds. Regulating terminal voltage of generator, increasing generator efficiency and maximum power tracking are the control objectives. Finally using the linearized state space model of system, a complementary robust Hcontroller will improve transient response of the system considering its uncertainties in the aerodynamic parameters. Simulation results show that the proposed controller damps the power oscillation more rapidly and improves stability of overall system.
