Abstract

DC-DC converter is a variable structure control system inherent due to the characteristics of the power switch. Sliding mode control technology is ideally suited for variable structure control system. In this paper, the sliding mode controller is designed based on the hysteresis modulation. The sliding surface parameters and the width of the hysteresis loop are given. Finally, a simulation of BUCK circuit based on Saber is built to verify the sliding mode controller. Simulation results show that the controller has good dynamic characteristics and robustness.
