AI总结:

针对具有未知状态的不确定非线性多智能体系统,本文提出一种结合改进调节函数、Lyapunov函数、事件触发策略、输出反馈观测器和RBF神经网络的事件触发观测器固定时间一致性控制方法,消除了Zeno行为并通过仿真验证了有效性。

摘要:

本文提出了一种在多智能体系统(MASs)中实现固定时间跟踪一致性控制的新方法。区别于对传统控制器的依赖,我们的创新控制器融合了改进的调节函数和Lyapunov函数,以保证稳定性和收敛性。此外,我们实施了一种事件触发策略,旨在降低更新频率,同时采用输出反馈观测器来有效处理不可测状态。为应对未知函数和代数环问题带来的挑战,我们选用了径向基函数神经网络(RBF NNs),因其具有优越的性能。我们的方法成功消除了Zeno行为,并确保系统在一个狭小定义的集合内保持稳定。所提方案的有效性通过两个示例性仿真算例得到了验证。

英文摘要:

This paper introduces a novel approach for achieving fixed-time tracking consensus control in multiagent systems (MASs). Departing from the reliance on traditional controllers, our innovative controller integrates modified tuning and Lyapunov functions to guarantee stability and convergence. Furthermore, we have implemented an event-triggered strategy aimed at reducing the frequency of updates, alongside an output-feedback observer to manage unmeasured states effectively. To address the challenges posed by unknown functions and algebraic-loop problems, we opted for radial basis function neural networks (RBF NNs), chosen for their superior performance. Our methodology successfully mitigates Zeno's behavior and ensures stability within a narrowly defined set. The efficacy of our proposed solution is validated through two illustrative simulation examples.
