CPS Architectures

Abstract: Developing cyber-physical systems involves multiple engineering domains, e.g., timing, logical correctness, thermal resilience, and mechanical stress. In today's industrial practice, these domains rely on multiple analyses to obtain and verify critical system properties. Domain differences make the analyses abstract away interactions among themselves, potentially invalidating the results. Specifically, one challenge is to ensure that an analysis is never applied to a model that violates the assumptions of the analysis.

Abstract: Modern cyber-physical systems interact closely with continuous physical processes like kinematic movement. Software component frameworks do not provide an explicit way to represent or reason about these processes. Meanwhile, hybrid program models have been successful in proving critical properties of discrete-continuous systems. These programs deal with diverse aspects of a cyber-physical system such as controller decisions, component communication protocols, and mechanical dynamics, requiring several programs to address the variation.

This extended abstract summarizes another facet of research under this project.
