Abstract: This thesis studies the consensus control of a group of agents connected via a dynamically changing communication network where the states of the agents lie within individually-defined constraints. It proposes two new algorithms for the cases where the state of each agent is a scalar and a vector respectively. Both algorithms use the edge weights as the working variables to enforce satisfaction of the constraints. The convergence and consensus of the states under reasonable assumptions for both algorithms are provided and the proof can be of independent interest. The proposed algorithms have the advantage that they preserve many of the desirable properties of the standard unconstrained consensus algorithm: the consensus value is independent of the sequence of network changes; and the average of the states remains a constant for all time steps. The proposed algorithm for the scalar case is also adapted to solve a real world vehicle to grid (V2G) problem. Simulation results are provided to verify the application of the proposed algorithm to the V2G problem.
