摘要

This paper investigates a group consensus problem of multi-agent systems with sampled data.A distributed linear consensus protocol is first designed to solve the group consensus problem,and then the dynamics of all the agents are presented with a linear estimation-based sampling period.By analyzing convergence properties of the dynamics,some necessary and sufficient conditions based on the sampling period are established for the agents reaching the group consensus.Finally,a simulation result is presented to demonstrate the effectiveness of the theoretical results.
