Advanced Control and Dynamic Real-time Optimization for Large-scale Processes
Senior Research Scientist, System Dynamics and Optimization Group
United Technologies Research Center
Current advances of optimization algorithm and software enable us to solve large-scale optimization problems online. This improves the economic performances of dynamic real-time optimization (D-RTO) and economic nonlinear model predictive control (NMPC). This talk discusses my PhD work in this area and a large-scale air separation unit (ASU) is used for simulation study. Around 6% cost reduction is achieved by the D-RTO compare to the set-point tracking NMPC in a demand response setting. In addition, offset-free control formulation based on the first-principle model is developed in the presence of plant-model mismatch. Finally, novel economic D-RTO formulations with guaranteed nominal stability property are proposed and significant economic benefits are observed.
