Efficient optimization algorithms for optimal operation of chemical processes
The operation of chemical processes is affected by multiple disturbances, such as changes in product demand and in the inlet conditions of the process. Rolling horizon-based strategies, such as Model Predictive Control, have been widely used to handle disturbances and guarantee safe and optimal operation. The efficiency of such strategies depends on the efficient repeated solution of optimization problems. Our group aims to develop computationally efficient solution methods by 1) exploiting the underlying structure of such problems, 2) developing tractable reduced-order models, and 3) combining optimization theory with artificial intelligence.
