Inductive Learning for Fault Diagnosis

There is a steadily increasing need for autonomous systems that must be able to function with minimal human intervention to detect and isolate faults, and recover from such faults. In this paper we present a novel hybrid Model based and Data Clustering (MDC) architecture for fault monitoring and diagnosis, which is suitable for complex dynamic systems with continuous and discrete variables. The MDC approach allows for adaptation of both structure and parameters of identified models using supervised and reinforcement learning techniques. The MDC approach will be illustrated using the model and data from the Hybrid Combustion Facility (HCF) at the NASA Ames Research Center.
