论文摘要
本文根据成对观察者结构为线性系统的最小订购时间未知的输入观察者提供了一个框架。首先为线性系统提出了最小的指定时间观察者，而无需未知输入，可以通过寻求线性方程系统的唯一解决方案来精确估计状态。为了进一步释放计算负担，设计了指定时间观察者的另一种形式。对于具有未知输入的通用线性系统，对系统动力学和测量输出都作用，模型重新配置是使未知输入的效果解脱出未知输入的效果的，并且现有的降级定期未知的输入观察者与可能的最小订单指定时间观察者之间的差距。基于重建的模型，提出了最小订购的指定时间未知的输入观察者，以实现对线性系统的状态估计，并在任意小的预设时间内使用未知输入。然后，将最小订单指定的未知输入观察者应用于线性多代理系统的完全分布的自适应输出反馈无攻击共识协议的设计。
This paper presents a framework on minimal-order appointed-time unknown input observers for linear systems based on the pairwise observer structure. A minimal-order appointed-time observer is first proposed for the linear system without the unknown input, which can estimate the state exactly at the preset time by seeking for the unique solution of a system of linear equations. To further release the computational burden, another form of the appointed-time observer is designed. For the general linear system with the unknown input acting on both the system dynamics and the measured output, the model reconfiguration is made to decouple the effect of the unknown input, and the gap between the existing reduced-order appointed-time unknown input observer and the possible minimal-order appointed-time observer is revealed. Based on the reconstructed model, the minimal-order appointed-time unknown input observer is presented to realize state estimation of linear system with the unknown input at the arbitrarily small preset time. The minimal-order appointed-time unknown input observer is then applied to the design of fully distributed adaptive output-feedback attack-free consensus protocols for linear multi-agent systems.
