Dynamic Adaptive Terminal Sliding Mode Control for DC-DC Converter

Abstract

Abstract. Inherent time-varying and heavy nonlinearity make DC-DC converters have many difficulties in control. A kind of dynamic terminal sliding mode control method is designed in this paper. To make it suitable for DC-DC converter suffering unknown border disturbances, an adaptive term is introduced in the designing of sliding mode control law. This scheme can make the system reach steady state quickly without chattering, and have good robustness to external disturbances and inner parameter variations. Simulation results show the effectiveness of this approach.
