TLDR
An experimental investigation into a hybrid back-stepping control proposed for the output voltage regulation of DC-DC buck converter is carried out in this article, where the proposed hybrid control algorithm utilizes a backstepping procedure in conjunction with a robust sliding mode control mechanism to counter both matched and mismatched uncertainties.Abstract:
An experimental investigation into a hybrid back-stepping control proposed for the output voltage regulation of DC-DC buck converter is carried out in this paper The proposed hybrid control algorithm utilizes a backstepping procedure in conjunction with a robust sliding mode control mechanism to counter both matched and mismatched uncertainties An experimental prototype of buck converter is fabricated and controlled with the hybrid control scheme in the laboratory The dynamic response under wide variation of operating points is investigated The control scheme is further extended to a discontinuous conduction mode buck converter which is even more nonlinear in nature A DSP based DS1103 platform is used to conduct experimentation Experimental results demonstrate a satisfactory transient and steady state performance of both output voltage and inductor currentread more
