Special Issue Information

Dear Colleagues,

A cyber-physical system (CPS) is a tightly coupled integration and coordination of computing elements, communication components, and physical resources. A multitude of wired and/or wireless communication/sensor networks connect these computing elements and physical resources. It is insufficient to study each of the following in isolation since a CPS is not their union, but their intersection: embedded computers, control theory, sensor and communication networks, physical resources, decision theory, data fusion, and knowledge discovery. Their joint dynamics must be studied together and this is what set this emerging discipline apart from these individually established fields. Before deploying a CPS, a formal modeling, analysis, and verification must be performed on the entire system, as well as its components, to ensure the CPS's safety, performance, and resilience. This Special Issue is devoted to the latest research in CPS and solicits papers in the following (but not limited to) topics:

  • Real-Time and Embedded Systems
  • Design Space Exploration and Synthesis
  • Control and Optimization
  • Automatic Optimization of Specifications and in Compilers, and Code Generators
  • Timing and Performance Analysis
  • Timing Analysis of Functional reactive systems
  • Model-based Testing
  • Correct-by-Construction
  • Requirements Modeling and Analysis
  • Model-driven Engineering
  • Application of Formal Methods in the design and validation of embedded systems
  • Safety Analysis
  • Fault Tolerance and Resilience
  • Sensor Networks
  • Code Generator Verification
  • Machine Learning
  • Data Fusion and Mining
  • Security

Title: Efficient Evaluation of Wireless Real-time Control Networks
Authors: Peter Horvath, Mark Yampolskiy, Yuan Xue, Xenofon Koutsoukos and Janos Sztipanovits
Affiliations: Vanderbilt University; E-Mail: Xenofon.Koutsoukos@vanderbilt.edu
Abstract: In this paper, we present a system simulation framework for design and Performance evaluation of complex wireless cyber-physical systems. We describe the simulator architecture, and the specic developments that are required to simulate cyber-physical systems relying on multi-channel, multihop mesh networks. We introduce realistic and efficient physical layer models and a system simulation methodology which provides statistically significant performance evaluation results with low computational complexity. The capabilities of the proposed framework are illustrated on the example of WirelessHART, a centralized real-time multi-hop mesh network designed for industrial control and monitor applications.

Title: Optimization and Control of Cyber-Physical Vehicle Systems

Abstract: Cyber-Physical Systems (CPS) are composed of tightly-integrated computation, communication, and physical elements. Medical devices, buildings, mobile devices, robotics, transportation, and energy are application domains that can benefit from CPS co-design and optimization techniques. Cyber-physical vehicles are rapidly advancing due to progress in real-time computing, control, and artificial intelligence. Multidisciplinary/multi-objective design optimization enables vehicle systems to be designed to maximize efficiency, capability, and safety while online regulation enables the vehicle to be responsive to disturbances, modeling errors, and uncertainties. A CPS is cooperatively optimized or co-optimized over both cyber and physical systems which have historically been designed separately then integrated. A CPS is cooperatively regulated or co-regulated when cyber and physical resources are commanded in a manner that is responsive to both cyber and physical system properties. This paper will review research in CPS that focuses on co-optimization and co-regulation schemes for CPS with focus on mobile robotic and vehicle applications. Time-varying sampling patterns, sensor scheduling, anytime control, feedback scheduling, task scheduling, and resource sharing will be examined.

Title: Cyber-Physical Systems: A Fundamental Intellectual Challenge
Authors: Edward A. Lee

Abstract:
The term cyber-physical systems (CPS) refers to the integration of computation and networking with physical processes, where sensors and actuators act as gateways between the cyber world of information technology and the physical world. Although many of the elements of CPS are familiar and not altogether new, as an intellectual subject, CPS is pushing hard at the frontiers of engineering methods, putting severe stress on the abstractions and techniques that have proven so effective in separated cyber and physical worlds. Notions of time and dynamics (the evolution of the state of a system in time) differ in these two worlds, and the engineering abstractions that we have built to cope with them do not mesh very well. While the engineering abstractions used in separated cyber and physical spaces are key enablers of the high-tech revolution of the 20th century, when they are brought together, key properties of these abstractions break down. For example, in the semantics of all widely used programming languages, the physical time that it takes to perform any action is irrelevant to the correctness of the execution of the program. Only the sequence of actions matters, a key property of all algorithmic cyber-world abstractions. But when these actions affect the physical world, the time at which they are performed matters. Lacking good abstractions that mesh key properties of these two worlds, engineering practice today is forced into a prototype-and-test style of design. This paper explains how we can do better.
