Abstract: This paper investigates control algorithms for wind turbine systems driven permanent magnet synchronous generator (PMSG). Direct torque control (DTC) method and backstepping approach are used. Also, generator side and grid-side converter with filter are used as the interface between the wind turbine and grid. The generator side rectifier controls the velocity of the PMSG with maximum power point tracking (MPPT) technique. The grid-side converter is used to inject the extracted power into the electrical network and to sustain the DC-bus voltage. Lyapunov stability theory is employed to found the conditions for the existence of the backstepping approach. The simulation results using Matlab/Simulink verify the effectiveness of the proposed controllers.

Keywords: variable speed-wind energy system; PMSG; permanent magnet synchronous generator; MPPT; maximum power point tracking; DTC; direct torque control; backstepping; Lyapunov theory; grid.
