This paper presents the comparison of three different strategies for the control of a doubly fed induction generator (DFIG) in wind energy conversion systems (WECS). Three of the most widespread and well-performing control approaches are implemented in an experimental setup based on a digital signal processor (DSP), namely, vector control, direct torque control, and direct power control. Said control methods are reviewed and their performances analyzed and compared on the basis of simulations and experimental results. The qualitative and quantitative comparison results thus obtained are likely to be of great interest to engineers and researches involved in the field of DFIG-based WECS.
