N2 - This paper presents a novel robust approach for buck converters voltage tracking by utilizing the high-order fully actuated (HOFA) theory. Initially, the HOFA model of the buck converter is derived, followed by an analysis of disturbances encountered in real-world scenarios. In order to mitigate the adverse consequences arising from imprecise or abrupt alterations in circuit parameters, a robust tracking controller is devised to enhance the overall robustness of the system. Ultimately, simulations are performed to compare the proposed controller with the dual-loop PI controller. The results indicate that the proposed controller exhibits a quicker dynamic response and greater robustness compared to the dual-loop PI controller. Additionally, the process of selecting parameters of this method is simpler and more convenient.
