Project List (Active)

Actuator Prognostics
Project Lead: Edward Balaban
This project concentrates on detecting and classifing incipient fault conditions in Electro Mechanical Actuators (EMA) at any point during their lifetime which can be used to provide an acurate picture of EMA component health to maintenance crews, enabling on-demand, selective servicing.

Automated Contingency Management (ACM)
Project Lead: Abhinav Saxena
The Automated Contingency Management (ACM) technology aims at accommodating impending failure conditions in an automated fashion. In general it performs a multi-objective constrained optimization problem for resource reallocation and system reconfiguration of low-level and high-level controllers in a hierarchical manner. The ACM considered here focuses in particular how prognostic information can be integrated and processed to carry out such reconfiguration tasks more efficiently.

Battery Prognostics
Project Lead: Abhinav Saxena
Develop algorithms that predict end-of-charge and end-of-life for batteries (prognosis) based on rapid assessment of state-of-charge (SOC) and state-of-health (SOH) (diagnosis) coupled with anticipated environmental and load conditions. Perform subscale experiments on batteries to demonstrate prognostic capability.

Data-Driven Prognostics
Project Lead: Kai F Goebel, Ph.D.
Develop algorithms that are not based primarily on physics-based models but that instead learn remaining life from training data. Issues tackled here are the need to deal with sparse time series data, to provide a fair uncertainty estimate, and to deal with the validation problem.

Distributed Prognostics
Project Lead: Sankalita Saha
Distributed prognostics is the next step in evolution of ISHM systems. They involve a coordinated health management of a system by using a distributed architecture of smart sensor devices. These devices monitor the health of individual subsystems. When any component/sub-system triggers the possibility of a failure requiring more attention, these devices work in coordination with each other to estimate the RUL (remaining useful life) and the health implications for the whole system.

Electronics Prognostics
Project Lead: Jose Celaya
Investigate damage propagation mechanisms for critical electrical components in select avionic equipment. Specifically, understand the impact of aging due to thermo-cycling, electric overstress, and vibration on MOSFETs, IGBTs, etc., and develop models for damage propagation.

Prognostic Data Repository
Project Lead: Kai Goebel
The Prognostics Data Repository is a collection of data sets that have been donated by various universities, agencies, or companies. The data repository focuses exclusively on prognostic data sets, i.e., data sets that can be used for development of prognostic algorithms. Mostly these are time series of data from some nominal state to a failed state. Many data sets are from real systems.
