We develop in this paper a sliding mode control of the stator powers of the doubly fed induction generator (DFIG), which is used within a wind energy conversion system (WECS). The elements of the state vector, used for control, are assumed available via measurements except the components of the rotor flux, which are estimated by a sliding mode observer. No rotor current sensor is required. The controller...
In this paper, the power factor of a grid-connected photovoltaic inverter is controlled using the input output Feedback Linearization Control (FLC) technique. This technique transforms the nonlinear state model of the inverter in the d–q reference frame into two equivalent linear subsystems, and then applies a pole placement linear control loops on this subsystem in order to separately control the...
