论文摘要
分散的控制系统被广泛用于多种情况和应用。为了使这些系统正常运行并实现其所需目标，必须在代理之间传播信息，这需要连接到网络。为了减少可能通过网络进行的攻击机会，我们设计了一种事件触发的网络连接和通信机制，以最大程度地减少必须连接到网络的时间量，进而降低了通信成本。该机制仅是本地信息的函数，并确保无攻击方案中整体系统的稳定性。我们的方法通过考虑代理并不总是连接到网络来接收其他代理商的关键信息，并考虑通信图是无方向性和连接的场景，从而将自己与当前分散事件触发的控制策略区分开来。提供了描述此网络连接和通信协议的算法，并通过仿真说明了我们的方法。
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 opportunities for 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 considering scenarios where agents are not always connected to the network to receive critical information from other agents and by considering scenarios where the communication graph is undirected and connected. An algorithm describing this network connection and communication protocol is provided, and our approach is illustrated via simulation.
