MULTI-OBJECTIVE PREDICTIVE PROCESS OPTIMIZATION WITH CONCURRENT PROCESS SIMULATION

摘要

A system and method for controlling a process includes simulating the process and producing a simulated output (MVss,CVss) of the process, developing in an optimizer 504 a set of target values MVt, CVt, AVt, based on measured inputs MV, CV, AV from the process and based on the simulated output from the process simulator, and producing multiple control outputs configured to control the process based on the set of target values during each operational cycle of the process control system. The simulated outputs include one or more predicted future values up to the steady state of the process.
