This paper investigates the consensus tracking problem for linear and nonlinear partial difference multi-agent systems with switching communication topology and control delay. A discrete distributed consensus protocol with initial value learning is designed for each agent using relative local measurements of neighboring followers, considering spatio-temporal discretization and initial state deviation, by employing a D-type iterative learning approach. The necessary and sufficient conditions are obtained through rigorous mathematical analysis, ensuring solvability of the consensus tracking control of the MASs under the switching of the communication topology. After applying the designed protocol, the consensus tracking error between any two agents can converge to zero in terms of the L2 norm and along the positive direction of the iteration axis. Finally, simulation examples are presented to validate the effectiveness of the protocol and theoretical results.
In this paper, the consensus tracking problem for the linear and nonlinear partial difference multi -agent systems with switching communication topology and control delay is investigated. Based on relative local measurements of neighboring followers, while considering spatio-temporal discretization and initial state deviation, a discrete distributed consensus protocol with initial value learning is designed for each agent via D-type iterative learning approach. Through rigorous mathematical theoretical analysis, the necessary and sufficient conditions are obtained. Under the switching of the communication topology, these conditions ensure that the consensus tracking control of the MASs can be solved. After applying the designed protocol, in the sense of the L2 norm and along the positive direction of the iteration axis, the consensus tracking error between any two agents can converge to zero. Finally, some simulation examples are used to demonstrate the validity of the protocol and theoretical results. (c) 2022 ISA. Published by Elsevier Ltd. All rights reserved.
