Robust multivariable predicting control method based on uncertain color model

Abstract

This invention relates to one dye machine module formula multi-variable prediction robust bar H infinity control method, which determines one dye machine mode formula multiple step prediction robust H infinity control method through data collection, process resolution, prediction control, robust H infinity control technique; using the control method to reduce uncertain factors color impact.

Description

technical field [0001] The invention belongs to the field of information technology and relates to automation technology, in particular to a robust H∞ control method based on model algorithm multivariate prediction for a dyeing machine. Background technique [0002] The final product of dyeing is mainly reflected in the color, and the key to determine whether the color of the finished product meets the customer's requirements lies in the pre-treatment and dyeing of the gray fabric. In the pre-treatment of domestic gray cloth, after the gray cloth is processed in each process, the process parameters of the semi-finished product are unstable, resulting in unstable dyeing production control parameters, poor reproducibility of the product during processing, and the same formula and production control parameters for the first time There will be different results from the second production, which will lead to a lack of credibility in the technical parameters of the production. At...
