摘要：This brief explores the mixed H∞ passive control issue for switched systems in network environment. Considering that system parameters may switch due to various factors, the persistent dwell-time (PDT) switching mode is employed to model this phenomenon. Attackers may insert false data into the system through the information network, thereby disrupting the normal operation of the system. And this behavior is likely to occur probabilistically. The main objective of this article is to establish an efficient dynamic event-triggered mechanism. The core idea of this mechanism is to only perform data transmission tasks when the trigger conditions are not met, thereby reducing unnecessary calculation and resource consumption. By incorporating dynamic variables and applying an exponential decay function, a triggered mechanism is established. Additionally, a mode-dependent non-fragile controller has been devised. This controller has the ability to ensure systems stability in adverse network environments. Lastly, the effectiveness of the proposed control scheme is illustrated via a boost converter circuit. ? 2024 Asian Control Association.
