Design of Robust Control Based on R∞ Approach of DFIG for Wind Energy System

摘要

This paper presents the robust control H-infinity (H_∞) of active power and reactive power of doubly fed induction generator (DFIG) for used on wind energy system. The study consists in presenting in brief the DFIG model and the main tools of H_∞ theory for designing a robust controller of active and reactive power, which achieved a satisfying robustness in dynamic performances, then it is applied to the control of DFIG. The simulation results prove that the application of H_∞ controller for active power and reactive power, given the high robustness in dynamic performance. however, the electrical and mechanical parameters uncertainty is large.
