A Saturated Higher Order Sliding Mode Control Approach for DC/DC Converters

This paper presents a novel approach of designing saturated Higher-Order Sliding Mode (HOSM) controllers for a class of DC/DC converters. Specifically, the proposed controller aims at guaranteeing boundedness and smoothness of the duty cycle feeding the Pulse-Width-Modulator. The novel control architecture consists of the so-called Bounded Integral Control (BIC) combined with a discontinuous HOSM control algorithm. The main strength of the proposed approach is its general applicability to a large class of DC/DC converters. Numerical results testify the effectiveness of the proposed approach.
