%X To deal with the undesirable performance and the low disturbance-rejection of the separated control for a double-fed induction generation(DFIG) based on a simplified model; we propose an accurately linearized decoupling control for the DFIG. First, we develop an integrated model for the assembly of electronic devices and the DFIG, and then, derive its inverse model by using the inverse system theory. This inverse model is then accurately linearized and installed in front of the original system. Thus, a pseudo linear system is developed, which is then synthesized based on the internal-model-control(IMC) theory to improve the robustness, realizing a high-performance control for the DFIG. Simulation results and experimental data validate the desirable performance and high robustness, the suppression of dc-bus voltage fluctuations, the reduction of the size of electrolytic capacitor, and the enhancement of the reliability of the wind generation system.
