Cyber-Physical Systems Engineering: The Advanced Power Grid

Abstract: hysical (CP) systems must address ing domains such as automotive, mical, aerospace, manufacturing, civil cture, and medical device systems, eye to how the fault tolerance, , decentralized control, and social f these systems influence their design. wer transmission systems are one such m and form a rich environment for the f several inherent problems. First, stems form one of the largest and most ly inter-connected networks ever d their scale makes controlling them ly difficult. Recent federal mandates gulation further increase the difficulty ol. Heavier power transfers resulting dependent ownership and potentially ead use of distributed energy on will make power systems gly vulnerable to cascading failures in small series of events can lead to a lackout. The envisioned Advanced Grid must include support for lized energy generation and sion controllers, whose local actions oordinated for integrated and efficient f the power grid as a whole.

Interoperation and Adaptation for Real-World Computing

Abstract: This paper discusses a consumer centric view of cyber physical systems and its requirements. It proposes using adaptation through observation based predictions to achieve predictable time and reliability. It proposes new directions in security research that is based on consumer electronics needs. It stipulates that interoperation is crucial and new methods for programming what happens between machines rather than within machines, are required. Finally, systems and theory must meet and verification and online model checking is proposed to achieve an increase in robustness.

Industrial Challenges in the Composition of Embedded Systems

Abstract: This paper describes a wide range of challenges faced by system designers in developing embedded and networked embedded systems (today's Cyber Physical Systems — CPS). These challenges derive from the complexity of the environment that the systems will need to operate in, coupled with emerging needs to continually increase system capabilities. Environmental complexities include the operation of systems in System-of-Systems (SoS) environments. System complexities posing challenges in embedded systems composition include the ever-increasing desire for on-board vehicle autonomy, and requirements for multiple safety criticalities co-existing within a software suite embedded in a vehicle. These complexity issues are driving dramatic increases in sizes of embedded real-time vehicle software loads. This brings concomitant increases in software development timelines and difficulty in system composition, verification, validation, and certification. The software engineering challenges are daunting, resulting in software being an ever increasing cost and schedule driver in emerging new system developments.
