报告题目：A Robust Distributed Model Predictive Control Framework for Consensus of Multi-Agent Systems with Varying Delays and Input Constraints
In the past two decades, much research effort has been devoted to the distributed coordination of the multi-agent systems (MAS) since it finds broad applications in numerous areas such as connected vehicles, smart grids, and sensor networks. As one of the fundamental control problems for the MAS, consensus requires that all agents achieve an agreement of common interest based on the local and neighboring information. Nonetheless, reaching consensus becomes more challenging when the MASs are subject to constraints and varying communication delays in real-world applications. In this talk, the consensus problem of a general linear discrete-time MAS with input constraints and bounded time-varying communication delays will be discussed, and a robust distributed model predictive control (DMPC) framework for consensus, integrating the offline consensus design with online DMPC optimization to exploit their respective advantages, will be proposed. Specifically, each agent is equipped with an offline consensus protocol depending on its immediate neighbors' estimated states. Then, the estimation errors propagated over time due to inexact neighboring information are proved bounded under some mild assumptions. Further, a robust DMPC strategy is deliberately designed to achieve robust consensus while satisfying input constraints. It is theoretically shown that, with the suitably designed cost function and constraints, the feasibility of the associated optimization problem can be recursively ensured. We further provide the consensus convergence result of the constrained MAS in the presence of bounded varying delays. Simulations examples illustrate the effectiveness of the developed method.
