NDLI: Design and implementation of a robust switching strategy for DC

Abstract	In this study, a novel robust switching rule is designed for DC–DC converters utilising switched systems’ theory. The converter dynamic is described in the form of linear switched affine systems with constant external input and then, sliding-mode switching controller is developed to ensure robust asymptotic stability of the desired equilibrium point for the system. The inherent robustness of the sliding-mode switching rule leads to efficient regulation of the output voltage under load variations. Simulation results of the buck converter are presented to demonstrate the superiority of the proposed method compared with some of existing schemes in the literature. Finally, experimental results from a laboratory buck circuit are reported to confirm the applicability of the introduced scheme.
