Co-Design of Cyber Physical Systems

The analysis and synthesis of Cyber Physical Systems require an integrative approach of the study of the underlying physical and cyber components and their intricate and interactive interconnections. Their implementation using Distributed Embedded Systems (DES) requires the modeling and control of the entire CPS, where uncertainties may occur both in the physical and in the cyber parts. When multiple applications have to be controlled using a DES, often the underlying resources are shared. One of the main implications of this resource contention is the introduction of delays in the control messages reaching their intended destination. These delays in turn can degrade system performance and cause instabilities. We have developed several algorithms to co-design CPS to improve stability and resource utilization. The algorithms range from Adaptive schemes to using Switching Theory methods. We have introduced overrun strategies to effectively design network and controllers to improve resource utilization by one order of magnitude.

Health Monitoring of Offshore Field Infrastructure

Failure of offshore infrastructure can be catastrophic. We are working on Healthmonitoring of offshore infrastructure to determine vulnerabilities before failure occurs. this project is a collaborating work with Professor Sahraei at Temple University, and Professors Lattanzi and Zhang at George Mason University. We look into design hardware for undersea vehicle monitoring devices and predicting failures using advanced Finite Element Modeling.
