    面向动态全局任务的异构多智能体系统监督控制

    Supervisory Control of Heterogeneous Multi-agent Systems for Dynamic Global Tasks

    • 摘要: 在多智能体系统执行全局任务时,某个智能体的行为可能导致整个系统陷于阻塞状态。为解决这一问题,面向动态全局任务,采用不同智能体可以完成不同任务、或不同智能体以不同方法完成同一任务的异构多智能体系统,通过建立一种全新的多智能体系统监督控制方法,实现多智能体系统安全、无死锁地完成该动态全局任务。每个智能体被建模为一个独立的离散事件系统,借助模型检测技术,完成智能体是否具备执行特定任务能力的评估;针对每个具备执行特定任务能力的智能体,设计满足特定规范的监督控制器,以保障任务的无阻塞完成。将理论结果应用于一个多智能体系统,以验证其有效性。

       

      Abstract: When a multi-agent system are executing global tasks, the behavior of an individual agent may lead to the entire system getting stuck in a deadlock state. To address this issue, this paper focuses on a heterogeneous multi-agent system where different agents can perform different tasks or accomplish the same task using different methods for dynamic global tasks. A novel supervisory-control framework is proposed to guarantee that the dynamic global task is completed safely and without deadlocks. First, each agent is modeled as an independent discrete event system, and model checking techniques are used to assess whether an agent has the capability to perform a specific task. Next, for each agent capable of executing a specific task, a supervision controller is designed to meet specific standards to ensure the task is completed without blocking. Finally, the theoretical results are applied to a multi-agent system to validate its effectiveness.
