Optimal Control of Alumina Concentration in Aluminum Reduction Cell Based on Two-Layer Model Predictive Control

Key Points

• Improving alumina concentration can enhance the overall efficiency of aluminum production in reduction cells.
• The optimal control strategy achieved a reduction in concentration fluctuations, leading to smoother operations.
• Analysis using a two-layer model predictive control framework provides more precise regulation of alumina levels.
• This approach may enable more reliable aluminum production, but further validation in industrial settings is needed.
