Developing A First Course on Cyber-Physical Systems

Proceedings of the WESE'14: Workshop on Embedded and Cyber-Physical Systems Education - WESE'14, 2015

Effective and creative Cyber-Physical Systems (CPS) development requires expertise in disparate fields that have traditionally been taught in several distinct disciplines. At the same time, students seeking a CPS education generally come from diverse educational backgrounds. In this paper, we report on our recent experience of developing and teaching a course on CPS. The course addresses the following three questions: What are the core elements of CPS? How should these core concepts be integrated in the CPS design process? What types of modeling tools can assist in the design of Cyber-Physical Systems? Our experience with the first four offerings of the course has been positive overall. We also discuss the lessons we learned from some issues that were not handled well. All material including lecture notes and software used for the course are openly available online.

Teaching Cyber-Physical Systems

Mechanical Engineering, 2017

This article discusses various aspects of a course on cyber-physical systems (CPS) in the educational programs of defense organizations. CPS are engineered systems that are built from, and depend upon, the seamless integration of computational algorithms and physical components. The article also highlights various objectives of the CPS course. A central challenge to deploying resilient CPSs involves the appreciation for the multi-disciplinary challenges and the lack of a unified framework for CPS analysis, design and implementation. A significant part of the course focuses on a case study in industrial control of a Vinyl Acetate (VAc) chemical plant. The course described herein presents fundamental concepts within the rapidly expanding field of CPS and has been tailored to and is well received by U.S. Naval Academy Systems Engineering senior level engineering students. The U.S. Naval Academy thrust in cyber security studies includes a new major, Cyber Sciences, and construction of a...

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.

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

AERO-beam: An open-architecture test-bed for research and education in cyber-physical systems

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015

As cyber-physical systems (CPS) increasingly become a part of daily life, a well-prepared workforce is needed to build and maintain, calling for new approaches and test-beds to introduce CPS concepts into classrooms at all levels. The literature has many examples of CPS relevant platforms, which are used successfully in research; however, especially the commercial ones are mostly closed-architecture and do not provide an in-depth engagement for the students in all aspects of the hardware and software. This paper introduces a novel platform, known as the AERO-Beam, which conveys many basics of CPS, while also introducing the dynamics and control fundamentals of quadcopters. Quadcopters are widely used in CPS projects, yet their limited batteries, rapid control response, and tendency to crash makes them difficult to use in CPS education. The AERO-Beam addresses the need in many ways, as demonstrated through a multi-level classroom implementation.

Design Techniques and Applications of Cyber Physical Systems: A Survey

2015

Cyber physical systems (CPSs) are new class of engineered systems which offer close interaction between cyber and physical components. The field of CPS has been identified as a key area of research and CPSs are expected to play a major role in the design and development of future systems. In this paper, we survey recent advancements made in the development and applications of cyber physical systems. We classify the existing research work based on their characteristics and identify the future challenges. We also discuss the examples of prototypes of CPSs. The aim of this survey is to enable researchers and system designers to get insights into the working and applications of CPSs and motivate them to propose novel solutions for making wide-scale adoption of CPS a tangible reality.

TEACHING CYBER-PHYSICAL SYSTEMS USING MIT APP INVENTOR 2

A Cyber-physical System (CPS) is defined as a system which combines computation and communication abilities along with monitoring and/or control entities in the physical environment. This definition shows how crucial the use of sensors and actuators are because they bridge between the cyber and the physical worlds. Currently, smartphones are equipped with many sensors. There is no doubt that smartphones are becoming, to many people, the primary communication device in their daily lives. Also, sensors allow smartphones to experience a revolution across a wide range of domains. Using sensors of smartphones in cyber-physical systems introduces mobile cyber-physical applications that are defined as computer systems which process and respond to data from the physical space and make decisions which influence it. It is anticipated that as sensors become smaller and cheaper, more markets will get introduced. MIT App Inventor is a blocks-based programming tool which simplifies building Android applications. It targets several audiences like educators, employees, volunteers, designers, product managers, researchers, and entrepreneurs. It deals with many types of sensors which makes it a great educational tool to teach cyber-physical systems for undergraduate and graduate students. Furthermore, this teaching methodology will enhance the students' skills in terms of dealing with this enormously growing market of smartphones and the world of applications. This paper presents several scenarios and examples of using MIT App Inventor 2 in a class setting to deal with AccelerometerSensor, Clock, Microphone, LocationSensor, and OrientationSensor.

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.

Acumen: An Open-Source Testbed for Cyber-Physical Systems Research

Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering, 2016

Developing Cyber-Physical Systems requires methods and tools to support simulation and verification of hybrid (both continuous and discrete) models. The Acumen modeling and simulation language is an open source testbed for exploring the design space of what rigorousbut-practical next-generation tools can deliver to developers of Cyber-Physical Systems. Like verification tools, a design goal for Acumen is to provide rigorous results. Like simulation tools, it aims to be intuitive, practical, and scalable. However, it is far from evident whether these two goals can be achieved simultaneously. This paper explains the primary design goals for Acumen, the core challenges that must be addressed in order to achieve these goals, the "agile research method" taken by the project, the steps taken to realize these goals, the key lessons learned, and the emerging language design.
