网络物理系统将数字和模拟设备、接口、网络、计算机系统等与自然和人造物理世界相结合。这些系统中行为的内在互连和异质组合使得它们的分析和设计成为一项具有挑战性的任务。在网络物理应用中强加的安全和可靠性规范，通常会转化为严格的健壮性标准，加剧了问题。不幸的是，最先进的系统分析和设计工具无法应对网络物理系统的内在复杂性。适合分析和设计网络物理系统的工具必须允许物理(或连续动力学)和网络(或计算组件)的组合，并处理各种类型的扰动，如外部干扰、时间延迟和系统故障。本文提出了一种用于网络物理系统分析和设计的混合控制系统方法。由于能够捕捉连续和离散动态，混杂系统模型[1]是研究网络物理系统的一个非常自然的框架。本文概述了混合控制理论文献中适用于网络物理系统的建模、分析和设计的方法。这些想法在整篇文章的几个例子中得到了说明。
Cyber-physical systems combine digital and analog devices, interfaces, networks, computer systems, and the like with the natural and man-made physical world. The inherent interconnected and heterogeneous combination of behaviors in these systems makes their analysis and design a challenging task. Safety and reliability specifications imposed in cyber-physical applications, which are typically translated into stringent robustness standards, aggravate the matter. Unfortunately, state-of-the-art tools for system analysis and design cannot cope with the intrinsic complexity in cyber-physical systems. Tools suitable for analysis and design of cyber-physical systems must allow a combination of physical (or continuous dynamics) and the cyber (or computational components), as well as handle a variety of types of perturbations, such as exogenous disturbances, time delays, and system failures. This article proposes a hybrid control systems approach to analysis and design of cyber-physical systems. Due to the capability of capturing continuous and discrete dynamics, hybrid system models [1] are a very natural framework for the study of cyber-physical systems. This article provides an overview of methods from the literature of hybrid control theory that are suitable for modeling, analysis, and design of cyber-physical systems. The ideas are illustrated in several examples throughout the article.
