Moisture control method and system in humidification process based on fuzzy feed-forward feedback algorithm

Abstract

The invention discloses a moisture control method in the humidification and humidification process based on a fuzzy feed-forward feedback algorithm, which comprises the following steps: obtaining relevant data of tobacco sheets in the humidification and humidification process; automatically identifying the collected brand information, and obtaining the corresponding batches of tobacco sheets Physical characteristics, the physical characteristics include at least the target outlet moisture content, and the range of water addition is obtained according to the target outlet moisture content; the inlet moisture content, outlet moisture content and mass flow rate of the smoke sheets collected during the rehumidification and humidification process are determined, When the inlet moisture content, the outlet moisture ratio and the mass flow rate of the smoke sheet are in normal working condition, the rehumidification and humidification process is controlled. The present invention finally realizes the goal of controlling the moisture in the humidification process, stabilizing the outlet moisture of the cigarette sheet, improving the qualified rate of the cigarette sheet and reducing the production cost of the cigarette. The method and system of the invention can not only improve the robustness and control precision of the system, but also quickly eliminate the deviation caused by the disturbance.

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.
