论文摘要
分子通信（MC）可以通过通过散布信号分子介导的反馈控制进行空间分散的分子机器人的合作。但是，对于MC通道的常规分析框架主要考虑单向通信的动态，缺乏反馈相互作用的影响。在本文中，我们为双向MC系统提出了一个通用控制理论建模框架，该框架能够以系统的方式通过MC捕获反馈控制的动力学。所提出的框架不仅考虑了分子扩散的动力学，而且还考虑了分子机器人的边界动力学，该动力学由于分子传输/接收过程捕获了影响整个反馈系统的性能而引起的滞后。因此，控制理论中的方法可用于系统地分析反馈系统的各种动力学特性。我们基于提出的框架执行频率响应分析，以显示MC通道以所需的控制带宽传输信号的一般设计指南。最后，通过显示满足给定规范的特定MC通道的分步设计过程来证明这些结果。
Molecular communication (MC) enables cooperation of spatially dispersed molecular robots through the feedback control mediated by diffusing signal molecules. However, conventional analysis frameworks for the MC channels mostly consider the dynamics of unidirectional communication, lacking the effect of feedback interactions. In this paper, we propose a general control-theoretic modeling framework for bidirectional MC systems capable of capturing the dynamics of feedback control via MC in a systematic manner. The proposed framework considers not only the dynamics of molecular diffusion but also the boundary dynamics at the molecular robots that captures the lag due to the molecular transmission/reception process affecting the performance of the entire feedback system. Thus, methods in control theory can be applied to systematically analyze various dynamical properties of the feedback system. We perform a frequency response analysis based on the proposed framework to show a general design guideline for MC channels to transfer signal with desired control bandwidth. Finally, these results are demonstrated by showing the step-by-step design procedure of a specific MC channel satisfying a given specification.
