Resilient consensus for multi-agent systems with quantized communication

Abstract

In this paper, we investigate the resilient consensus problem for multi-agent systems with quantized communication. We assume that each agent in the network can only exchange quantized information with its neighbors. A novel quantized-data based secure control law with built-in security mechanism is proposed to achieve consensus in the presence of attack agents. It is shown that for a directed network, as long as the number of attack nodes is bounded in each node' neighborhood, the consensus can be achieved with a given sufficient network connectivity. Finally, we offer a numerical example to demonstrate the validity of the derived results.
