Abstract

An electrical power circuit consisting of a doubly fed induction generator and two power-electronic converters is considered. A mathematical model is given, and the flatness of the model is shown. The freedom in the choice of one component of the flat output chosen is used in order to minimize the power losses in the system. Trajectory tracking controllers for the machine and the grid side converter are developed using a backstepping approach. The results are supported by numerical simulations.
