Prescribed-time Convergent Distributed Multiobjective Optimization with Dynamic Event-triggered Communication
<|reference_start|>Prescribed-time Convergent Distributed Multiobjective Optimization with Dynamic Event-triggered Communication: This paper addresses distributed constrained multiobjective resource allocation problems (DCMRAPs) within multi-agent networks, where each agent has multiple, potentially conflicting local objectives, constrained by both local and global constraints. By reformulating the DCMRAP as a single-objective weighted $L_p$ problem, a distributed solution is enabled, which eliminates the need for predetermined weighting factors or centralized decision-making in traditional methods. Leveraging prescribed-time control and dynamic event-triggered mechanisms (ETMs), novel distributed algorithms are proposed to achieve Pareto optimality within a prescribed settling time through sampled communication. Using generalized time-based generators (TBGs), these algorithms provide more flexibility in optimizing accuracy and control smoothness without the constraints of initial conditions. Novel dynamic ETMs are designed to work with generalized TBGs to promote communication efficiency, which adjusts to both local error metrics and network-based disagreements. The Zeno behavior is excluded. Validated by Lyapunov analysis and simulations, our method demonstrates superior control performance and efficiency compared to existing methods, advancing distributed optimization in complex environments.<|reference_end|>
