Application of Expert System in the Analysis of Aluminum Reduction Cell

Abstract

Aluminum reduction cell is a non-linear, multivariable coupling time-varying system, inside which a large number of physical and chemical reactions occur. Meanwhile, aluminum reduction cell is often influenced by disturbance outside, which can easily cause instability of aluminum reduction cell. For the analysis of aluminum reduction cell, a kind of expert system based on blackboard structure is proposed, which can analyze aluminum reduction cell by combination of rule-based reasoning and case-based reasoning based on the data of blackboard structure and information from knowledge base. For an aluminum plant, experiment result has shown that expert system based on blackboard structure can analyze the aluminum reduction cell effectively, and it has certain engineering practicability.
