摘 要：Cyber-physical systems (CPS) can be described as smart systems that encompass computational (i.e., hardware and software) and physical components, seamlessly integrated and closely interacting to sense the changing state of the real world. These systems involve a high degree of complexity at numerous spatial and temporal scales and highly networked communications integrating computational and physical components. CPS are enabling a new generation of smart systems and the economic impacts could be enormous. The disruptive technologies emerging from combining the cyber and physical worlds could provide an innovation engine for a broad range of U.S. industries, creating entirely new markets and platforms for growth. New products and services will bring the creation and retention of U.S. jobs. The nation will also benefit through greater energy and national security, enhanced U.S. competitiveness, and improved quality of life for citizens.
