✦ Synopsis
Abstracts 086 A Knowledge-Based Approach to Optimizing and Maintaining Cngeneration Facilities A. Hofmann, pp 211-216 system, allows automatic tuning of the industrial controllers.
An application to superheated steam temperature control of a drum boiler is considered.
This paper describes a combination of optimal control and expert-system techniques, unified by a knowledge-based approach, to provide a powerful tool for running and maintainin.g cogeneration plants. The basic optimization problem hs solved using linear programming (LP) techniques. The novelty of the knowledge-based approach is in the way that the LP is set up. Instances of the classes of a defined hierarchy of components are created and connected by the user in a schematic. This object-oriented approach provides an unprecedented level of generality. The objects in the schematic can be used in other roles: as the basic data structures for heuristic diagnostics, and as a graphic user interface to the operator.
