摘要

分子通信（MC）通过扩散信号分子介导的反馈控制，实现了空间分散分子机器人的协作。然而，传统的MC通道分析框架大多考虑单向通信的动力学，缺乏反馈交互的影响。在本文中，我们为双向MC系统提出了一个通用的控制理论建模框架，该框架能够通过MC系统地捕捉反馈控制的动力学。所提出的框架不仅考虑了分子扩散的动力学，还考虑了分子机器人的边界动力学，该动力学捕捉了由于分子传输/接收过程影响整个反馈系统性能而产生的滞后。因此，控制理论中的方法可以用于系统地分析反馈系统的各种动力学特性。我们在所提出的框架的基础上进行了频率响应分析，以展示MC信道以所需控制带宽传输信号的通用设计指南。最后，通过展示满足给定规范的特定MC信道的逐步设计过程来证明这些结果。

A Control-Theoretic Model for Bidirectional Molecular Communication Systems

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.

期刊介绍： As a result of recent advances in MEMS/NEMS and systems biology, as well as the emergence of synthetic bacteria and lab/process-on-a-chip techniques, it is now possible to design chemical “circuits”, custom organisms, micro/nanoscale swarms of devices, and a host of other new systems. This success opens up a new frontier for interdisciplinary communications techniques using chemistry, biology, and other principles that have not been considered in the communications literature. The IEEE Transactions on Molecular, Biological, and Multi-Scale Communications (T-MBMSC) is devoted to the principles, design, and analysis of communication systems that use physics beyond classical electromagnetism. This includes molecular, quantum, and other physical, chemical and biological techniques; as well as new communication techniques at small scales or across multiple scales (e.g., nano to micro to macro; note that strictly nanoscale systems, 1-100 nm, are outside the scope of this journal). Original research articles on one or more of the following topics are within scope: mathematical modeling, information/communication and network theoretic analysis, standardization and industrial applications, and analytical or experimental studies on communication processes or networks in biology. Contributions on related topics may also be considered for publication. Contributions from researchers outside the IEEE’s typical audience are encouraged.
