Description
Technical field
The present invention relates to a kind of control method, especially a kind of linear control method for correcting of tobacco cutting perfuming trueness error.
Background technology
Cigarette product needs to add a certain proportion of spices in the pipe tobacco production process, increase the fragrance of product.Spices,, is sprayed on the pipe tobacco after atomizing the perfuming nozzle of spices pressurized delivered to the cylinder by the perfuming pump through pipeline from the perfuming jar.
Tobacco business flavoring and casing system is the same substantially, and the raising of charging precision is mainly by adopting high accuracy detecting element and outstanding control algolithm.
The method that tobacco business improves the perfuming precision generally is to revise reinforced ratio, calculate actual reinforced actual ratio according to reinforced cumulative amount and material integrating flowmeter, relatively revise with preset proportion again, the method of revising mainly contains following several: the one, publication number is: the patent disclosure of CN1785074A a kind of perfuming/charging process of tobacco leaf throwing line, get reinforced cumulative amount and the material integrating flowmeter of a period of time and calculate actual reinforced actual ratio, relatively revise with preset proportion again, what of LOAD CELLS measurement material are this patent just utilize, a kind of detection method of weight of material is provided, openly how not revise reinforced ratio automatically in the open file, do not arrive concrete ratio modified computing method yet.And there is the shortcoming of real-time difference in this technology.
The 2nd, publication number is the control method that CN1262907A discloses a kind of flavour addition in material: calculate charging precision according to reinforced cumulative amount, material cumulative amount and reinforced preset proportion, significantly revise reinforced ratio when precision is big, there is the concussion fluctuation of size conversion in the precision hour small size ratio of feeding in raw material of revising.The two-dimensional fuzzy controller of this patent and publication number are: the method for CN1785074A is similar, but replaces instantaneous perfuming ratio with the spices flow of a period of time and the ratio of mass flow, does not also provide concrete control algolithm.Change than detecting reinforced flow with liquid level, reduced the cost of flowmeter, tobacco business all uses mass flowmenter, electromagnetic flowmeter that the feed liquid flow is detected at present, and the method falls behind.This patent just illustrates that to a charging system two-dimensional fuzzy controller core control algolithm does not provide.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of method relatively more succinct reliable, in real time the feed molar ratio row are revised, reached the linear control method for correcting of the tobacco cutting perfuming trueness error of linearisation correction.
