基于增量式PID算法的香精施加系统设计
Flavoring system design based on incremental PID algorithm
摘要
Abstract
In order to solve the problem that the spray weight could not be adjusted and controlled according to the weight change of the tobacco sheet during the manufacturing process of heat-not-burn tobacco product in real time,a flavoring system was designed based on incremental PID algorithm.The flavoring system was composed of weig-hing unit,screw pumps,nozzles,and flow sensors.The weight of the tobacco sheet roll was obtained through the weighing unit in real time,then the spray weight was calculated according to the theoretical calculation model,and the screw pumps were driven to output target flow to the nozzles based on incremental PID algorithm,the real-time spray weight was got from the flow sensors,and at last tobacco flavor was sprayed on the tobacco sheet.The results showed that the spray weight could be adjusted and controlled according to the weight change of the tobacco sheet in real time,the maximum overshoot of the flavoring system was 1%,and the maximum adjustment time was 1.8 s,the system had good tracking performance.The deviation ratio of the spray weight was 0.23%～0.52%between the detection value and the theoretical value,the variation of the spray weight within samples was 3.11%～4.17%.It showed that the flavoring system could realize accurate,uniform and stable application.关键词
