A process plant simulator developed within an object-oriented expert system shell

摘要

The efficient solving of process control problems often requires manipulating a wide spectrum of knowledge representations ranging from analytical knowledge to qualitative knowledge. These tendencies have been causing a growing interest formethods that are flexible enough to accommodate knowledge-based paradigms. In the paper, the simulator design of the amorphous SiO{sub}2 precipitation process is described. From the control point of view, the process is a typical semibatch processcontaining discrete, as well as continuous dynamics. The simulator is developed in G2, which is an environment to the development of real-time expert systems and has been effectively used on a problem containing a great diversity of model descriptions.
