Computational intelligence in a real-time SCADA system to monitor and control continuous casting of steel billets

An intelligent module has been developed for a continuous billet casting mould in which features are extracted from rapidly-changing data (~200 Hz). The system mimics how a human reads a graph or time-series chart and instantly recognizes aspects and trends about process operation and stability. A real-time expert system then uses this preprocessed data for intelligent supervisory or adaptive control. The tools for real-time filtering use elements of the new field known as computational intelligence. Mathematical primitives and heuristic processing allow rapid analysis to provide symbolic information. This paper describes the concept of CI as used to support real-time monitoring of continuous casting of steel billets
