By Fco I. Gamero, J. Colomer, J. Meléndez and X. Berjaga


Abstract: This paper presents a tool developed to obtain qualitative trend representations from signals, Qualtras. The aim of such a type of description is to offer an understandable representation of process behavior based on the concept of qualitative episode. The tool is intended to be used as a numeric to qualitative interface for supervisory applications. The applicability of this tool is demonstrated in a monitoring application of a steam generator. 1
