Abstract

This paper investigates the state estimation and event-triggered control for positive nonlinear multi-agent systems. Firstly, a proportional–integral observer is established to estimate the states of the considered nonlinear positive multi-agent systems based on the matrix decomposition method. Then, a dynamic event-triggered mechanism is constructed, and a control protocol is proposed based on the proportional–integral observer and event-triggered mechanism. By combining linear programming with linear co-positive Lyapunov functions, the considered multi-agent systems are guaranteed to be positive and achieve consensus. Moreover, by introducing three new variables and a finite vector, the final convergence point can be changed based on the given vector. Finally, two illustrative examples demonstrate the validity of the proposed theoretical results.

基于比例积分观测器的非线性正多代理系统动态事件触发共识协议

本文研究了正非线性多代理系统的状态估计和事件触发控制。首先，基于矩阵分解方法，建立了一个比例积分观测器来估计所考虑的非线性正多代理系统的状态。然后，构建了动态事件触发机制，并提出了基于比例积分观测器和事件触发机制的控制协议。通过将线性规划与线性共正 Lyapunov 函数相结合，保证了所考虑的多代理系统是正的并能达成共识。此外，通过引入三个新变量和一个有限向量，最终收敛点可根据给定向量进行改变。最后，两个示例证明了所提理论结果的正确性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
