Abstract
Automatic control systems with sophisticated control algorithm can be very large and complex. In order to improve the automatic process control, it is important to develop fault diagnosis strategy. A hierarchical scheme of fault detection and isolation based on Decision Support System (DSS) is presented. For fault diagnosis, a knowledge based procedure is required. In addition to analytic symptoms, heuristic information have to be taken into account. A pattern recognition method, a unified representation of all symptoms, and a fuzzy expert system are integrated in the diagnostic tool. This approach is applied to sensor fault detection in a chemical plant, and compared with different methods.
