Abstract
TRANSCEND uses qualitative transient analysis methods for monitoring and diagnosis of dynamic systems to overcome complexity and convergence issues that arise in numerical processing, especially for nonlinear systems. Generating qualitative features from real signals, the signal to symbol transformation problem, is a challenging task. This paper discusses model-driven methods for generating symbolic feature descriptions of magnitude and slope changes in noisy continuous data. Experiments have been successfully conducted on faults introduced into the cooling system of an automobile engine.
