Incremental networked predictive control of multi‐agent systems with plant‐model mismatch and random communication constraints

IET Control Theory & Applications, 2022
In this paper, we discuss the cooperative output tracking problem for networked multi‐agent systems (NMASs) with plant‐model mismatch as well as random communication constraints in the forward and feedback channels of each agent.
