Comparison of First- and Second-Order Sliding-Mode Controllers for a DC-DC Dual Active Bridge

Abstract

This paper compares four sliding-mode control strategies for a dual active bridge. The proposed control algorithms define different switching functions resulting in first-and second-order controllers, and using both discontinuous and continuous sliding-mode algorithms. The paper details the design stage and includes simulation and experimental tests to better compare the performance for each control scheme.
