Abstract
Decentralized control systems are widely used in a number of situations and applications. In order for these systems to function properly and achieve their desired goals, information must be propagated between agents, which requires connecting to a network. To reduce vulnerabilities to attacks that may be carried out through the network, we design an event-triggered mechanism for network connection and communication that minimizes the amount of time agents must be connected to the network, in turn decreasing communication costs. This mechanism is a function of only local information and ensures stability for the overall system in attack-free scenarios. Our approach distinguishes itself from current decentralized event-triggered control strategies by including measurements in the system model, by not needing to implement any reachability analysis, and by considering scenarios where agents are not always connected to the network to receive critical information from other agents. Algorithms describing these network connection and communication protocols are provided, and our approach is illustrated via simulation.
