Agreement of General Sampled-data Multi-agent Systems

This paper focuses on looking for the maximum allowable sampling period for multi-agent systems with general linear dynamical agents. As long as the sampling period is less than the bound, there exists a linear agreement protocol solving the agreement problem of the sampled-data multi-agent systems. Firstly, the agreement problem is converted to the simultaneously stabilizing problem of some specific systems. Secondly, the maximum allowable sampling period for SISO sampled-data multi-agent systems is provided based on the instable eigenvalues of continuous-time system matrix. Then by solving the H_∞ optimal control problem of certain system with uncertainty, an allowable bound of sampling period is obtained.
