Cyber-Physical Systems

Cyber-physical systems (CPS) are engineered systems that are built from, and depend upon, the seamless integration of computation and physical components. Advances in CPS will enable capability, adaptability, scalability, resiliency, safety, security, and usability that will expand the horizons of these critical systems. CPS technologies are transforming the way people interact with engineered systems, just as the Internet has transformed the way people interact with information. New, smart CPS drive innovation and competition in a range of application domains including agriculture, aeronautics, building design, civil infrastructure, energy, environmental quality, healthcare and personalized medicine, manufacturing, and transportation. CPS are becoming data-rich enabling new and higher degrees of automation and autonomy. Traditional ideas in CPS research are being challenged by new concepts emerging from artificial intelligence and machine learning. The integration of artificial intelligence with CPS, especially for real-time operation, creates new research opportunities with major societal implications. While tremendous progress has been made in advancing CPS technologies, the demand for innovation across application domains is driving the need to accelerate fundamental research to keep pace. At the same time, the CPS program seeks to open new vistas for the research community to think beyond the usual cyber-physical paradigms and structures and propose creative ideas to address the myriad challenges of today's systems as well as those of the future that have not yet been designed or fielded. The CPS program aims to develop the core research needed to engineer these complex CPS, some of which may also require dependable, high-confidence, or provable behaviors. Core research areas of the program includecontrol, data analytics, and machinelearning including real-time learning for control, autonomy, design, Internet of Things (IoT), mixed initiatives including human-in- or human-on-the-loop, networking, privacy, real-time systems, safety, security, and verification. By abstracting from the particulars of specific systems and application domains, the CPS program seeks to reveal cross-cutting, fundamental scientific and engineering principles that underpin the integration of cyber and physical elements across all application domains. The program additionally supports the development of methods, tools, and hardware and software components based upon these cross-cutting principles, along with validation of the principles via prototypes and testbeds. This program also fosters a research community that is committed to advancing education and outreach in CPSand accelerating the transition of CPS research into the real world. All proposals must include the following as part of the Project Description:

• AResearch Descriptionthat describes the technical rationaleand technical approach of the CPS research, including the challenges that drive the research problem and how the research integrates cyber and physical components.This section must also describe how the research outcomes are translational to other application domains. Specifically, it must include:
  • A subsection titled "CPS Research Focus" which describes the cyber-physical system attributes of the challenge problem and clearly identifies the core CPS research areas addressed in which the novel and foundational research contributions are being made. This is intended as not a list of core areas but a focused discussion with content
• An Evaluation/Experimentation Plan that describes how proposed concepts will be validated and outlines the metrics for success;
• A Project Management and Collaboration Plan that summarizes how the project team is ideally suited to realize the project goals and how the team will ensure effective collaboration;

NSF is working closely with multiple agencies across the federal government, including the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S & T); the U.S. Department of Transportation (DOT) Federal Highway Administration (FHWA); and the U.S. Department of Agriculture National Institute of Food and Agriculture (USDA NIFA, hereafter referred to as NIFA). Proposals for three classes of research and education projects-differing in scope and goals-are supported through the CPS program:

• Smallprojects mayrequest a total budget of up to $600,000 for a period of up to 3 years. They are well suited to emerging new and innovative ideas that may have high impact on the field of CPS. Small projects proposals may be submitted at anytime during the year-long annual submission window.
  
• Medium projects may request a total budget ranging from $600,001 to $1,200,000 for a period of up to 3 years. They are well suited to multi-disciplinary projects that accomplish clear goals requiring integrated perspectives spanning the disciplines. Medium Projects proposals may be submitted at anytime during the year-long annual submission window.
  
• Frontierprojects must address clearly identified critical CPS challenges that cannot be achieved by a set of smaller projects. Furthermore, Frontier projects should also look to push the boundaries of CPS well beyond today's systems and capabilities. Funding may be requested for a total of $1,200,001 to $7,000,000 for a period of 4 to 5 years. Note that the Frontier projects have a specific deadline.
