Subject to the theory and technology of existing network systems and physical systems, the development of CPS is facing enormous challenges. This paper first introduces the concept and characteristics of CPS and analyzes the present situation of CPS researches. Then the development of CPS is discussed from perspectives of system model, information processing technology and software design. At last it analyzes the main obstacles and key researches in developing CPS.

Cyber-Physical Systems: A Literature Review

Cyber-physical systems (CPSs) are smart systems that depend on the synergy of cyber and physical components. They link the physical world (e.g. through sensors, actuators, robotics, and embedded systems) with the virtual world of information processing. Applications of CPS have the tremendous potential of improving convenience, comfort, and safety in our daily life. This paper provides a brief introduction to CPSs and their applications. Introduction The term " cyber-physical system " (CPS) was coined in 2006 by Helen Gill of the US National Science Foundation (Henshaw, 2016). As the name suggests, CPS has both cyber (software control) and physical (mechanism) elements. Cyber-physical systems (CPSs) are engineered systems that are designed to interact seamlessly with networks of physical and computational components. These systems will provide the foundation of our critical infrastructure and improve our quality of life in many areas. CPSs and related systems (such as IoT and industrial Internet) have the potential to impact various sectors of the economy worldwide. CPS is basically an engineering discipline, focused on technology and modeling physical processes (differential equations, stochastic processes, etc.) with mathematical abstractions. In a CPS, computing elements coordinate and communicate with sensors, which monitor cyber and physical indicators and actuators. CPS is also similar to the Internet of Things (IoT), sharing the same basic architecture (Cyber-physical system, 2017). It is also related to embedded systems. While an embedded system is

Challenges and Current Solutions of Cyber Physical Systems

The interaction among people has been increased rapidly due to advances in internet and increased use of smart phones that are now available at all price ranges. The next step is to improve communication among machines by connecting the machines and giving intelligence to them to communicate among machines by connecting the machines and giving intelligence to them to communicate with other machines and also to interact with people. Cyber Physical Systems (CPS) are a natural consequence of an increasingly connected physical world. CPS have wide range of applications at the same time there are several challenges to implement these systems. In order to identify the challenges and current solutions and propose research possibilities in different areas of CPS we survey the literature of this area. Our approach is to identify the challenges in different areas of CPS including monitoring and actuator infrastructure, communication network, computation and control operation. We identify different elements in each area and explain the nominal and abnormal behaviour of all the elements. Finally we will explain the current solutions to deal with the abnormal behaviour of the elements.

A Survey Paper on Cyber Physical Systems

— Cyber-physical systems (CPS) are engineered systems that are built from, and depend upon, the seamless integration of computational algorithms and physical components. CPS technology will transform the way people interact with engineered systems. CPS will bring advances in personalized health care, emergency response, traffic flow management, and electric power generation and delivery, as well as in many other areas now just being envisioned. This paper aims for providing an insight into this emerging multidisciplinary methodology.

Science and Engineering of Cyber-Physical Systems (Dagstuhl Seminar 11441)

Today, a new category of engineering systems is emerging that combines the physical with the computational in a holistic way: Cyber-physical systems (CPS). The key property of these systems is that functionality and salient system properties are emerging from an intensive interaction of physical and computational components. Traditional separation along engineering disciplines in the design of such systems leads to various quality, maintainability and evolutionary problems, and integrated theories and engineering techniques are urgently needed. The purpose of the seminar is to bring together researchers from the field, from both academia and industry to discuss the new scientific foundations and engineering principles for the vastly emerging field of CPS.

Distributed Control of Cyber Physical System on Various Domains: A Critical Review

Systems

Cyber-Physical System (CPS) is a symbol of the fourth industrial revolution (4IR) by integrating physical and computational processes which can associate with humans in various ways. In short, the relationship between Cyber networks and the physical component is known as CPS, which is assisting to incorporate the world and influencing our ordinary life significantly. In terms of practical utilization of CPS interacting abundant difficulties. Currently, CPS is involved in modern society very vastly with many uptrend perspectives. All the new technologies by using CPS are accelerating our journey of innovation. In this paper, we have explained the research areas of 14 important domains of Cyber-Physical Systems (CPS) including aircraft transportation systems, battlefield surveillance, chemical production, energy, agriculture (food supply), healthcare, education, industrial automation, manufacturing, mobile devices, robotics, transportation, and vehicular. We also demonstrated the chal...

Cyber Physical System: Architecture, Applications and Research Challenges

Cyber world and physical world were considered as two different entities in the past decade. However, researchers have found that these two entities are closely correlated with each other after integration of sensor/actuators in the cyber systems. Cyber systems became responsive to the physical world by enabling real time control emanating from conventional embedded systems, thus emerging a new research paradigm named Cyber Physical System (CPS). In this article, we investigate major challenges in the integration of cyber world with physical world and its applications. In addition, we propose an architecture which contains several modules supporting the CPS. We found that every module in our proposed architecture has its own significance and can be applied to various applications.

Cyber-Physical Systems: Concepts, technologies and implementation principles

The practical implementations of the paradigm of cyber-physical systems appear in many different forms. However, they can be identified based on their distinctive characteristics such as distributed, multiscaled, dynamic, smart, cooperative, and adaptive. The objective of our explorative research was to cast light on the key notions, prevailing theoretical understanding, and engineering concepts, and to investigate the main principles and resources of implementation. First, a proposal is made to replace the standard architectural reasoning model with one which expresses the growing synergy between the enabling technologies. Opposite to the conventional view that differentiates the implementation technologies as cyber and physical technologies, this reasoning model introduces the class of synergic technologies. These technologies gradually dissolve the boundaries between cyber and physical as the difference between atoms and bits is disappearing due to current technological achievements, such as particle-based computing, molecular sensors and nano-actuators. Then, the paper gives a concise overview of the various physical, synergic and cyber technologies. Finally, the paper discusses the most important design and implementation principles. Its main conclusion is that though a huge number of publications are available concerning the paradigm, constituents, architectures and enabling technologies of cyber-physical systems, this domain of knowing and development is still in its infancy and many research questions should be addressed from multiple aspects.
