The goal of Phase I study was to investigate advanced pattern recognition techniques for use in fault diagnosis. Three individual experts have been developed based on Auto Associative Neural Networks (E-AANN), Kohonen Self Organizing Maps (KSOM), and the Radial Basis Function based Clustering (RBFC) algorithms. We have used a Matlab Simulink model of a Chiller system to test our algorithms. The set of individual experts are later managed by a Gated Expert algorithm which assigns the experts based on their best performance regions. In Phase II, we propose to implement our results on two dynamic systems. The first is a Chiller system at the Texas A&M University. The second is an engine under study in Pratt and Whitney under a contract to Professor George Vactsevanos from Georgia Tech. The end deliverable of Phase II will be a complete dynamic Case Based Reasoning (GED-CBR) system managed by a Gated Experts algorithm all coded in Matlab. GED-CBR will be highly applicable to dynamic systems that can benefit from the power of Dynamic Case Based Reasoning managed by a powerful Gated Experts architecture. It is expected that GED-CBR will find applications in prognostics of the nuclear reactor on board the JIMO spacecraft.
