Embodiment

[0128] Embodiment: The application of the self-adaptive model predictive control device of the present invention in the atmospheric distillation column of the atmospheric and vacuum plant. Description of the MPC design of the atmospheric pressure column of the atmospheric and vacuum plant

[0129] The atmospheric distillation column of the atmospheric and vacuum unit (referred to as the atmospheric column) is the most complicated and most difficult to control part of the atmospheric and vacuum unit. Figure 8 It is a simple flow chart of the atmospheric fractionation tower of an atmospheric and vacuum device in an oil refinery. According to different boiling points, crude oil is initially decomposed into different fractions in this tower. The column has four side-draw fractions and each has a side-draw splitter associated with it.

[0130] - kerosene (side draw fraction 1);

[0131] - Diesel (A.D.) for pipeline hybrid automotive diesel engines (A.D. is blended from four side dr...

Abstract

The invention discloses an adaptive model prediction control (MPC) device, comprising a MPC control module controlling the controlled process, an online recognition module and a control detection module, wherein the MPC control module is connected with the controlled process, the online recognition module and the control detection module, the online recognition module is connected with the control detection module and the controlled process, the control detection module is connected with the controlled process. When the MPC control module works, the online recognition module and the MPC control module operate together to automatically effectively complete the steps for the application of the MPC control module. When the MPC control module works online, the control detection module continuously detects the property of MPC and the quality of the model. When the control property is worse and the model has low quality, the control detection module starts the online recognition module to automatically maintain the MPC control module.

Description

technical field [0001] The invention relates to an adaptive model predictive control (MPC) device for a multivariable controlled process, which can be used to control industrial processes in process industries such as oil refining, petrochemical, chemical, metallurgy, food, papermaking and electric power. The present invention is relevant to Advanced Process Control (APC), in particular to Model Predictive Control (MPC) of industrial processes. The present invention can handle large-scale industrial processes with multiple control variables (MV) and multiple controlled variables (CV), and can also be used to control complex machinery and equipment. Background technique [0002] Model predictive control (model predictive control, MPC or: model predictive control,) has become a standard advanced control technology (APC), popularized in the refining and petrochemical industries (see Qinand Badgwell, 2003: A survey of industrial model predictive control technology ( Review of I...
