Expert systems in the process industries

1992

This paper gives an overview of industrial applications of real-time knowledge based expert systems (KBES's) in the process industries. After a brief overview of the features of a KBES useful in process applications, the general roles of KBES's are covered. A particular focus is diagnostic applications, one of the major applications areas. Many applications are seen as an expansion of supervisory control. The lessons learned from numerous online applications are summarized.

Expert control systems: An introduction with case studies

EOLSS: Encyclopedia of Life Support Systems--Control Systems,Robotics and Automation, vol. XII, 1995

This chapter gives a concise presentation of expert control on the basis of a generic architecture that involves the operators, the expert system, the control algorithm, auxiliary units (parameter estimator, fault detector) ,and the plant under control. Particular aspects covered are knowledge representation, knowledge acquisition, reasoning in expert control, real-time expert systems, expert system-based computer-aided control, and anticipatory systems.Three case studies are briefly described to clarify many of the above concepts.
