Through the analysis on the characteristics of aluminium electrolytic process, the method of comprehensive simulation and optimization of aluminium reduction equipment, technology and control techniques is put forward. Based on modern aluminium metallurgical engineering science, models and algorithms in three aspects, i.e., aluminium reduction equipment, technology and controllers can be organically combined to establish the comprehensive simulation and optimization models and algorithms; an on line comprehensive simulation and closed loop control system can then be set up by integrating the simulation, optimization and control. The system can realize not only the conventional static simulation calculations, but also dynamic simulation calculations in the closed loop control process, which, on one hand, provide a new method for the comprehensive optimization of aluminium reduction equipment, technology and control techniques and, on the other hand, play the role of enhancing the performance of the intelligent control system for aluminium reduction cells.
