Air injection control system

Abstract

The invention relates to the field of automatic production, and discloses an air injection control system. An NARX neural network model 1 and an NARX neural network model 2 are used for controlling air flow and predicting an air flow value respectively, and an NARX neural network establishes a dynamic recursive network of the models by introducing a time delay module and outputting feedback, input and output vector delay feedback is introduced into network training to form a new input vector, good nonlinear mapping capability is achieved, the input of the NARX neural network not only comprises the error of original gas flow, the control quantity and the input data of actual gas flow, but also comprises the trained corresponding output data; the generalization ability of the network is improved, so that the system has better prediction precision and adaptive ability in prediction of corresponding parameters of the gas flow compared with a traditional static neural network, and the single-chip microcomputer controller improves the precision, robustness and reliability of the control system.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an air injection control system. Background technique [0002] Nowadays, most of the existing archives and scanners used for the filing of important materials are contact scanning, using a combination of rollers and conveyor belts to transport paper. Because the physical characteristics of material paper are very sensitive, part of the paper is likely to be scanned during scanning. Adsorbed to the upper platen, while other parts are spread flat on the lower transparent placement plate, resulting in uneven flatness of the paper during scanning, and the problem that some scans are clear and some scans are not clear; in addition, it may also be caused by paper crumbs obscure the paper, or the paper is curled unevenly and the scan is incomplete. [0003] In addition, in the current scanning equipment, the controller has poor control accuracy, stability, timeliness and a...

[0002] Nowadays, most of the existing archives and scanners used for filing of important materials are contact scanning, using a combination of rollers and conveyor belts to transport paper, because the physical characteristics of material paper are very sensitive, and part of the paper is likely to be scanned during scanning. Adsorbed to the upper platen, while the other part is flat on the lower transparent placement plate, resulting in uneven flatness of the paper during scanning, and the problem that some scans are clear and some scans are not clear; in addition, it may also be caused by paper Incomplete scanning caused by crumbs covering the paper, or uneven curling of the paper

[0003] In addition, in the current scanning equipment, the controller has poor control accuracy, stability, timeliness and adaptability to the components during scanning, which affects the scanning effect.
