This is the wiki for the NSF CPS project CPS: Small: Energy-Aware Formal Synthesis for Supervisory Control and Information Acquisition in Cyber-Physical Systems
NSF award number: CNS-1738103. Project period: 10/01/2017 – 09/30/2021
PI: Stéphane Lafortune
Abstract
This project developed theoretical foundations and computational algorithms for synthesizing higher-level supervisory and information-acquisition control logic in cyber-physical systems that expend or replenish their resources while interacting with the environment. On the one hand, qualitative requirements capture the safety requirements that are imposed on the system as it operates. On the other hand, quantitative requirements capture resource constraints in the context of energy-aware systems. These dual considerations are needed in applications of cyber-physical systems where efficient management of resources must be accounted for in the dynamic operation of the system in order to achieve the desired objectives within a given energy or resource budget.
The approach that was developed is formal and model-based. It leverages a recently-developed unified framework for supervisory control and information acquisition in the higher-level control logic of cyber-physical systems, but it explicitly embeds quantitative constraints in the solution procedure in order to capture the energy or resources expended and/or replenished by the cyber-physical system as it interacts with its environment. This generic solution methodology is applicable to several classes of cyber-physical systems subject to energy/resource constraints. Software tools were developed to facilitate the transition of these results to application domains. Overall, this project impacted both the Science of Cyber-Physical Systems and the Engineering of Cyber-Physical Systems.
The results obtained in this project also supported our efforts on the problem of opacity enforcement by obfuscation, as described at: Obfuscation Project of the UMDES Group
