Visible to the public Science of Cyber-Physical System Integration

Abstract:

The tight integration of physical and information processes in CPS necessitates the development of a new systems science, which is simultaneously computational and physical. Dynamics, modeling, feedback, and control are central issues in CPS research. The unique challenges in CPS integration emerge from the heterogeneity of components and interactions.

Visible to the public Diagnostics and Prognostics Using Temporal Causal Models for Cyber Physical Systems – A Case of Smart Electric Grid

Abstract:

Motivation: Reliable and resilient operation of cyber-physical systems (CPS) of societal importance such as Smart Electric Grids is critical. Efficient models and tools to perform timely fault diagnostics and prognostics are needed for curtailing systemic failures such as power blackouts. Varying system state caused by the fluctuating power consumption, dynamic control actions, physical component degradation, and interactions with possible software anomalies make the failure analysis, prediction, and mitigation difficult.

Visible to the public Foundations Of Resilient CybEr-physical Systems (FORCES)

Abstract:

Cyber-Physical Systems (CPS) are being increasingly deployed in critical infrastructures such as electric-power, water, transportation, and other networks. These deployments are facilitating real-time monitoring and closed-loop control by exploiting the advances in wireless sensor-actuator networks, the internet of "everything," data-driven analytics, and machine-to-machine interfaces. CPS operations depend on the synergy of computational and physical components.

Visible to the public Diagnostics and Prognostics Using Temporal Causal Models for Cyber Physical Systems – A Case of Smart Electric Grid

Abstract:

Understanding failure in protection system using Temporal Causal Diagrams Situational awareness in large electrical systems and eventual fault source identification and possibly prognostics is a very challenging problem. State of the art relies on a network of protection devices that include relays to detect anomalies and engage circuit breakers to isolate the faulty component(s) in the system.

Visible to the public Science of Cyber-Physical System Integration

Abstract:

The objective of this project is to develop a science of integration for cyber physical systems (CPS). The proposed research program has three focus areas: (1) foundations, (2) tools and tool architectures, (3) systems/experimental research. The project has pushed along several frontiers towards these overall objectives. In the following, we describe selected accomplishments:
