摘要 多智能体系统由多个具有独立决策能力的智能体组成,其中每个个体都按照自己 的方式运行,它们之间相互依赖、协调互助。二十多年以来,多智能体的一致性问题 成为人们研究的焦点。本文针对非线性多智能体系统,利用 T-S 模糊函数逼近相邻智 能体非线性项的差值,从而得到了适用于非线性多智能体系统的一致性算法。 本文首先介绍了文中所用到的一些基础知识,包括图论的基本概念和矩阵论中的 几个定理。为了研究基于模糊控制的多智能体的一致性,初步介绍了几种多智能体系 统的模型和控制算法。 然后介绍了模糊控制的相关知识,并结合实际生活中的例子,讲述了如何用 T-S 模型来逼近非线性系统。
最后,本文研究了基于模糊控制的高阶非线性多智能体系统的一致性问题。利用 T-S 模糊函数逼近相邻智能体非线性项的差值,将原多智能体系统模型转化为一个T-S 模糊系统,然后构建李雅谱诺夫函数进行分析,得到了智能体状态趋于一致的充 分条件,并给出了一致性算法的设计步骤。编写 matlab 算法程序,并利用 Simulink 进行仿真,得到仿真结果,验证算法的有效性。

Abstract Multi-agent system is composed of multiple independent decision-making agent, in which each inpidual run in its own way, interdependent and coordinated between them。 More than 20 years since, the consistency of multi-agent problems become the focus of people study。 In view of the nonlinear multi-agent system, this paper USES t-s fuzzy function approximation nonlinear term difference of adjacent, and is suitable for nonlinear multi-agent system have been obtained the consistency of the algorithm。
This article first introduces in this paper, we used some of the basic knowledge, including the basic concept of graph theory and matrix theory in several theorems。 In order to study the consistency of multi-agent based on fuzzy control, a preliminary model of multi-agent system are introduced and the control algorithm。
Then introduces the related knowledge of fuzzy control, and combined with the examples in real life, tells the story of how to use the t-s model is used to approximate nonlinear systems。
Finally, this paper studies the high order nonlinear multi-agent based on fuzzy control system of the consistency problem。 Uses t-s fuzzy function approximation nonlinear term difference of adjacent, the original multi-agent system model is converted into a t-s fuzzy system, and then build yeli spectrum function analysis, obtained the sufficient conditions for the agent to have consistent state of, and presents a consistent design steps of the algorithm。 Write a matlab algorithm, and by using Simulink simulation, get the simulation results verify the validity of the algorithm。
Keywords: multi-agent system, t-s function, control rules and consistency issues
