A new design of a digital control system for the grid-connected doubly fed induction generator is described in this paper. A discrete-time state-space model of the controlled system is obtained in the stator stationary reference frame. Using this model, a discrete-time sliding mode based control system is designed. Its tasks are the grid synchronization and the direct power control. The discrete-time...
This paper proposes an algorithm technique for an asymmetric cascaded multilevel converter with one floating cell with reduced number of calculation. This control approach permits a unique DC source generate three-phase current with one main cell and one floating cell per phase. Main cells are handled by using a space vector control and floating cells are controlled by a predictive control algorithm...
