Tóm tắt

This paper addresses the design of a networked control system for dual-active bridge (DAB) DC-DC converters to track a prescribed output-voltage reference. Specifically, it tackles two primary challenges: the sampled-data control problem and time delay issues arising from networked communication. To this end, a mathematical model of the DAB DC-DC converter is formulated as a linear state-space system. Subsequently, an improved looped-functional and an additional discontinuous function are incorporated into the time-dependent Lyapunov function. Accordingly, sufficient stability and stabilization conditions are derived in the form of linear matrix inequalities (LMIs). Finally, simulation results are presented to validate the effectiveness of the proposed method.
