Feedback linearization control of Doubly-fed induction generator under an unbalanced voltage

In this paper, a control algorithm based on feedback linearization control for Doubly-fed induction generator is proposed. Feedback linearization is a way of transforming original system model into simple equivalent model and eliminating the non-linearity of the system characteristic. Therefore, system controller can be designed by linear control theory. This paper suggested a new control method for Doubly-fed induction generator has been suggested by using feedback linearization method. The improved performance is verified through feasibility test. The experimental results are provided to evaluate the performance of proposed control scheme comparing PI control with feedback linearization control.
