Moisture control method and system in moisture regaining and moistening process based on fuzzy feedforward feedback algorithm

Abstract

The invention discloses a moisture control method and system in the moisture regaining and moistening process based on a fuzzy feedforward feedback algorithm. The method comprises the following stepsthat related data of tobacco sheets in the moisture regaining and moistening process is acquired; collected mark number information is automatically recognized, physical characteristics of the tobaccosheets of the corresponding batch are obtained and at least comprise target output moisture content, and according to the target output moisture content, a range of the water addition amount is obtained; the collected input moisture content, output moisture content and tobacco sheet quality flow of the tobacco sheets in the moisture regaining and moistening process are judged, and when the inputmoisture content, the output moisture content and the tobacco sheet quality flow are in the normal work state, the moisture regaining and moistening process is controlled. The moisture control methodand system finally achieves the purposes that moisture control over the moisture regaining and moistening process is conducted, the output moisture of the tobacco sheets can be stabilized, the qualification rate of the tobacco sheets is increased, and the production cost of cigarettes is reduced. Through the moisture control method and system, the robustness and control precision of the system areimproved, and the deviation caused by disturbance can be quickly eliminated.

Description

technical field [0001] The invention relates to the technical field of moisture resurgence and humidification control, in particular to a method and system for controlling moisture in a rehumidification and rehumidification process based on a fuzzy feed-forward feedback algorithm. Background technique [0002] The moisture regain and humidification process mainly includes the loose moisture regain process, the flavoring and feeding process, and the temperature increasing and humidifying process. It is an important processing procedure for moisture control in the tobacco industry. The outlet moisture content is an important technical index in the humidification process, and its process stability has a direct impact on the subsequent process index. At present, there are many problems in the control of outlet moisture in the process of humidification and humidification, and the most prominent are three points: First, due to the time delay in the humidification and humidificatio...

Problems solved by technology

[0003] The traditional PID controller is simple in design and easy to operate, but it has a good control effect only when the controlled object has linear characteristics and the parameters are well matched. The controller cannot be adjusted accordingly, and the control effect will be poor.
