Comparative study of power control of DFIG using PI control and FeedBack Linearization Control

Abstract

This paper presents the decoupled power control for a DFIG (doubly-fed induction generator) system using PI Control and FeedBack Linearization Control (FBLC). Further the controller performances are verified for the parameter variation also. Using the parameters of the laboratory machine, simulations are carried out to verify the effectiveness of the two control schems viz., PI and FBLC in the MATLAB Simulink. Based on the simulation results it is found that the FBLC performs better than PI for the decoupled control of DFIG.
