| 英文摘要 |
| In this paper, event-triggered output feedback finite-time bounded control of linear systems is investigated.
Unlike asymptotic stability which only requires qualitatively that the system is bounded during inter-sample, for finite-time
boundedness, it is necessary to estimate the upper bound of the trajectory to ensure that the system meets the quantitative
requirements. Based on Lyapunov-like function, sufficient conditions are given to ensure finite-time boundedness of the
resultant closed-loop system and to avoid Zeno behavior in an emulation context. The conditions can be transformed into
linear matrix inequalities such that they are easy to be verified and used in practice. Moreover, an event-triggered rule with
variable parameters, which can improve the flexibility of design, is also proposed, aiming at conserving sources. Simulation
results are employed to verify main results proposed in this paper. |
