Consensus of a Class of Heterogeneous Networked System with Sampled-Data

This paper studies the consensus problem for a class of heterogeneous networked system. We first discretize the continuous-time networked system by sampled-data method. Then we convert the networked system into the reduced-order error system by a system transformation. Based on algebraic graph theory and matrix theory, a sufficient condition for the networked system to achieve consensus is obtained by analyzing the stable problem of the reduced-order system. Simulation example will be given to show the usefulness of the results.
