Models and model building in intelligent process control systems

A novel approach to the intelligent control of cogeneration plants comprising multiple-aspect modeling and model interpretation is presented. The most important characteristics of this approach are the following: (1) models represent the plant as well as the control system; (2) the control system is derived from this representation; (3) processing of sensory input signals is done in the context of the models; (4) control actions are determined based on the basis of the actual state of the plant and the models. This system has demonstrated that not only are the capabilities of the control system enhanced, but the system development efforts are reduced dramatically as well
