Applications of Cyber-Physical System: A Literature Review

Cyber-Physical System (CPS), a new generation of digital system, mainly focuses on complex interdependencies and integration between cyberspace and physical world. A CPS is composed of highly-integrated computation, communication, control, and physical elements. CPS is currently of interest in academia, industry, and government. However, a systematic and extensive review of research on CPS is not available. As such, this paper conducts an expanded literature review on applications of CPS by examining existing literatures from 2012 to 2017 in Scopus database. Specifically, 77 papers studying applications of CPS are grouped into 10 categories and reviewed. The contents of the papers in each research category are summarized. The challenges and trends of research on CPS are illustrated as well.
