Condensation of Information from Signals for Process Modeling and Control

This paper deals with processing and storage methods for large volume industrial process data measurements which enable the utilization of historical data for process understanding. In the context of hybrid systems, the focus is upon the steps commonly lumped under the category of analog to digital conversion (ADC), which is the interface between the continuous time world of the industrial process and the discrete time world of digital processing. In both cases a hybrid systems viewpoint prevails where continuous variable, discrete variable, and discrete event activities occur.
