Multi-objective predictive process optimization with concurrent process simulation

Abstract

A system and method for controlling a process includes simulating the process and producing a simulated output of the process, developing a set of target values based on measured inputs 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.

Description

[0001] related application [0002] This patent claims priority to U.S. Provisional Application Serial No. 60 / 742,322, filed December 5, 2005, the entire contents of which are hereby incorporated by reference , are expressly incorporated into this patent. technical field [0003] The present disclosure relates generally to process control systems in process plants, and more particularly to process optimization using process simulation and predictive models. Background technique [0004] Process control systems are widely used in factories and / or plants that manufacture products or control processes (eg, chemical manufacturing, power plant control, etc.). Process control systems are also used in the extraction of natural resources, such as oil and gas drilling and processing processes. Virtually any manufacturing process, resource extraction process, etc., can be automated through the application of one or more process control systems. It is believed that the process contr...

Problems solved by technology

However, the process optimizer cannot provide a solution if said solution does not exist within the predefined range and bounds

As a consequence, the process optimizer cannot provide solutions in every case
