Abstract
In this paper, the problem of modeling and control for DC-DC converter is investigated. A novel switched system model is established and an asynchronous control strategy is designed. Firstly, the DC-DC converter is modeled by the semi-Markov switched system with uncertainty and external disturbance. In which, the change of resistance parameter and the jump of input voltage are considered. Additionally, the sojourn-time of the switch is considered in the new model, in this way, it can be more accurately to depict the dynamic behavior of the plant. Then, in order to guarantee the stability of the plant, a state feedback asynchronous controller is proposed. Furthermore, the stability conditions of the closed-loop system with a prescribed H∞ index factor are given and the controller gains are solved. Finally, a numerical simulation and a practical experiment are executed to verify the superiority of proposed control strategies.
