Yang Yan, Lanlan Su, Vijay Gupta, Panos Antsaklis

摘要:

本文通过引入耗散性工具研究了数字通信网络上二维反馈系统的闭环$\mathcal{L}_2$稳定性。首先,连续的2-D系统的采样被认为是和分析表征的$QSR$ -耗散的采样系统。其次,利用输入-前馈-输出-反馈无源性(IF-OFP),即$QSR$ -耗散性的一种简化形式,研究了网络上两个2-D系统的反馈互联结构。然后,分析了通信链路中信号量化对2-D反馈量化系统耗散性退化的影响。此外,事件触发机制的2-D网络控制系统,同时保持闭环系统的$\mathcal{L}_2$稳定性的发展。最后给出了一个说明性的例子。

英文摘要:

This paper investigates the closed-loop $\mathcal{L}_2$ stability of two-dimensional (2-D) feedback systems across a digital communication network by introducing the tool of dissipativity. First, sampling of a continuous 2-D system is considered and an analytical characterization of the $QSR$-dissipativity of the sampled system is presented. Next, the input-feedforward output-feedback passivity (IF-OFP), a simplified form of $QSR$-dissipativity, is utilized to study the framework of feedback interconnection of two 2-D systems over networks. Then, the effects of signal quantization in communication links on dissipativity degradation of the 2-D feedback quantized system is analyzed. Additionally, an event-triggered mechanism is developed for 2-D networked control systems while maintaining $\mathcal{L}_2$ stability of the closed-loop system. In the end, an illustrative example is provided.
