| 英文摘要 |
| This paper deals with the problems of dissipativity and exponential stabilization for switched systems with
unstable subsystems and mixed time delays. First, in order to eliminate the adverse effects of unstable subsystems on
such time-delay systems, a novel switching signal design method is adopted in this paper, which combines slow switching
and fast switching with the mode-dependent average dwell time technique. And by using Lyapunov theory, sufficient
conditions for global exponential stability of closed-loop systems are given. Then, delay-dependent criteria are derived in
terms of linear matrix inequalities by employing dissipativity theory, multiple Lyapunov-Krasovskii functional approaches,
mode-dependent average dwell time technique and Jensen’s integral inequality, making the closed-loop system achieve
exponential stability and strict dissipativity. In addition, with the given premise of disturbance attenuation level, a set
of feasible controllers are established by solving some strict LMI conditions. Finally, a simulation example is given to
demonstrate the availability of the acquired methods. |
