Dynamic real-time optimization of distributed MPC systems

Real-time optimization (RTO) is a supervisory control algorithm that provides set-points to an underlying regulatory control system based on optimizing the plant economics. Industrial RTO systems typically utilize a steady-state model of the process, and are executed every few hours in order to track the economic optimum, as parameters affecting the plant conditions and process economics change (Marlin and Hrymak, 1997; Darby et al., 2011).
