This article studies finite-time H-infinity control for continuous-time-switched Takagi-Sugeno fuzzy systems with mode-dependent average dwell-time (MDADT) switching. The dynamic event-triggered mechanism is used to monitor data transmission, reducing the amount of transmitted data more efficiently compared to conventional static methods. The proposed control scheme is validated through simulation examples, demonstrating its effectiveness and advantages.
In this article, finite-timeH(infinity) control is studied for a kind of continuous-time-switched Takagi-Sugeno (T-S) fuzzy systems with mode-dependent average dwell-time (MDADT) switching. The dynamic event-triggered mechanism (ETM) is utilized to monitor the data transmission from the system plant to the controller, which more efficiently reduces the amount of transmitted data than the conventional static one. First, it is demonstrated that the adopted dynamic ETM can avoid the Zeno behavior, and also yield a larger minimal interexecution time compared with the static one. Then, an improved criterion of finite-time H-infinity performance is introduced by utilizing a novel Lyapunov-like function with an internal dynamic variable. Based on this criterion, a dynamic event-triggered controller is designed together with a switching signal subject to the MDADT property. Finally, the validity, and virtues of the proposed control scheme are verified by two simulation examples.
