Production, transportation systems and various other parts of critical infrastructure such as energy grids have traditionally been controlled via self-contained, centralized systems continuously monitored and reconfigured by humans. The ever-growing complexity and integration of these Cyber-Physical Systems (CPSs) into reconfigurable value chains (e.g. “Industrie 4.0”), however, require a radical change in control and communication strategies.

A shift towards real-time-capable communication systems for CPS control is required, however, can only be achieved by overcoming the traditionally loose coupling in the design of system components in networks (horizontal and vertical abstraction). Currently, the communication systems community as well as control systems researchers consider the components of the respective other field as a “black box” and abstract from their variations: Networks relay control system messages regardless their content and without being able to interpret their meaning and importance, while control systems only have very restricted notions of the system behavior on the network level. The question is how to derive generalizable co-design methods and metrics that support the development of universal networked CPSs. By taking information about the structure and capabilities of the network into consideration during development, control theory may be able to create distributed or more fault-tolerant control algorithms, while networks may in turn use additional knowledge about the control loops to avoid or mitigate situations of overload or decreasing channel qualities in settings with wireless control.

The purpose of this Dagstuhl Seminar is hence to enable a sharing of knowledge between the key communities relevant for the science of networked CPSs and cyber-physical networking (CPN) and to tackle the so-far strict abstractions and boundaries among the two key fields: control theory and communication. To this end, researchers from multiple fields, including computer science, communications, automation, control theory and from the application side shall be brought together in this seminar.

In the series Dagstuhl Reports each Dagstuhl Seminar and Dagstuhl Perspectives Workshop is documented. The seminar organizers, in cooperation with the collector, prepare a report that includes contributions from the participants' talks together with a summary of the seminar.

Furthermore, a comprehensive peer-reviewed collection of research papers can be published in the series Dagstuhl Follow-Ups.

Dagstuhl's Impact

Please inform us when a publication was published as a result from your seminar. These publications are listed in the category Dagstuhl's Impact and are presented on a special shelf on the ground floor of the library.
