中文摘要

      针对未知动力学模型非线性离散时间多智能体系统, 在信息传递过程中的数据量化问题, 以及智能体之间 的合作与竞争关系, 提出了一种数据驱动控制算法, 实现了多智能体系统的双向一致性跟踪控制. 首先, 利用紧凑形 动态线性化(CFDL)方法, 将未知动力学模型的非线性智能体转化为含有时变参数的数据模型, 并通过设计性能指 标函数获得时变参数的估计算法; 然后基于该数据模型, 利用代数图论和扇形界算法, 设计了一种量化数据驱动分 布式双向一致性跟踪控制协议, 并对其收敛性给出了严格的证明. 结果表明, 当多智能体系统存在数据量化时, 所 设计的控制协议仍可以保证双向一致性跟踪误差收敛到0. 最后, 通过仿真实验和对比实验, 进一步验证了该控制 协议的有效性和鲁棒性.

英文摘要

      In this paper, we investigate the data quantization problem of an unknown dynamics model of nonlinear discrete-time multi-agent systems (MASs) with collaborative and antagonistic relationships and propose a data-driven control algorithm for MASs to perform bipartite consensus tracking control. We first develop an estimation algorithm of the time-varying parameter by designing a performance index function through transforming the unknown dynamics model nonlinear agent into a data model with a time-varying parameter using the compact form dynamic linearization (CFDL) approach. We then design a quantized data-driven distributed bipartite consensus tracking control protocol based on the data model by employing the algebraic graph theory and the sector-bound approach. We also strictly prove the convergence property of the proposed algorithm. The results show that although the MASs subject to quantized data, the formulated protocol still guarantees the bipartite consensus tracking errors of MASs to converge to zero. Finally, the developed approach’s effectiveness and robustness are further verified through a numerical example and a contrast experiment.
