Improved dynamic response of a non ideal DC-DC boost converter using an Integral Sliding Mode Controller

Abstract

The real implementation of DC-DC boost converters controllers is slightly difficult due to their non minimum phase behavior and the non zero output voltage error. Integral Sliding Mode Controllers (ISMC)s have proved to be able to deal with this kind of converters and to eliminate the chattering phenomenon. In order to cancel the output voltage error, we apply in this paper, an ISMC to a detailed modelling of boost converter (by considering the associated parasites). Numerical and experimental comparative studies with the ideal case and the classical SMC verify the effectiveness and the robustness of this controller.
