摘要

摘要: 现有基于偏微分方程(Partial differential equation, PDE)的多智能体系统(Multi-agent system, MAS)编队控制方法要求智能体必须是密集分布的, 为打破这一限制, 提出一种新的基于常微分−偏微分方程(Ordinary differential equation-partial differential equation, ODE-PDE)的分析方法, 以解决稀疏−密集混合分布的大规模异构MAS编队问题. 首先, 通过设计特定的通信协议, 并基于空间离散系统部分连续化方法, 将原始大量的异构MAS的ODE动力学模型转化为由一个PDE 和少数几个ODE耦合而成的ODE-PDE 模型. 为更符合实际复杂场景, 将拓扑权值规定为半马尔科夫切换的, 且稀疏分布和密集分布智能体遵循不一致的切换规则. 其次, 针对无时滞和有时滞两种情形, 设计两种异步边界控制策略, 利用Lyapunov方法得到保证误差系统实际有限时间稳定的充分条件, 并得到停息时间和稳定阈值的计算规则. 最后, 两个广义的数值仿真进一步验证了所提方法的有效性.

Abstract: The existing formation control methods of multi-agent systems (MASs) based on partial differential equation (PDE) require that agents must be densely distributed. To break this limitation, this paper proposes a novel analysis method based on ordinary differential equation-partial differential equation (ODE-PDE), such that the formation problem of large-scale heterogeneous MASs with sparse and dense mixed distribution could be solved. First, the original numerous heterogeneous ODE dynamics models of MASs are transformed into an ODE-PDE model consisting of a PDE coupled to several ODEs through specific communication protocol design and partial continuum method of spatial discrete systems. To match realistic complex scenes better, the topological weights are designed to be semi-Markov switched, and the switching rules followed by sparsely and densely distributed agents are inconsistent. Second, two asynchronous boundary control strategies are designed for delay-free and time-delayed cases, respectively. The Lyapunov method is used to obtain sufficient conditions to ensure the practically finite-time stability of the error system, and the calculation rules of the settling time and stability threshold are provided. Finally, two generalized numerical simulations further verify the effectiveness of the proposed approach.
