Abstract:An intelligent fuzzy control system for the prebaked anode aluminum reduction cells was developed by comprehensively using intelligent control techniques including fuzzy control, neural networks and expert system, and the techniques of on-line simulation of "three fields" of aluminum reduction cell. Two-hierarchical distributed control pattern was used, and four sub-systems called real-time control, bath-temperature and freeze-profile on-line simulation, cell state diagnosis, and organization & supervision were designed for the control system. Running on the 160 kA prebaked anode aluminum reduction cells showed that the control system possesses good rubustness, high control accuracy, and good prospects of wide application for increasing production and saving energy.
