Abstract

The embodiment of the invention provides a tobacco leaf shredding charging precision control method and system. The method comprises the following steps of S1, inputting a charging precision error parameter and a charging precision error change rate parameter in a tobacco leaf shredding charging process into a preset fuzzy controller, and outputting a proportional coefficient of a PID controller by the preset fuzzy controller; and S2, based on the proportional coefficient, constructing the PID controller so as to control the charging accuracy during a tobacco leaf shredding charging process. By using the tobacco leaf shredding charging precision control method and system, the method of combining the PID controller and fuzzy control is used to control a charging accuracy error, and a proportional value Kp of the PID controller is dynamically adjusted through the fuzzy control so that for the different charging accuracy errors, different charging additional speeds are obtained. And thenthe charging precision error is reasonably improved so that a charging amount accords with a requirement in a tobacco leaf shredding process.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of tobacco flavor control, and more specifically, relate to a method and system for controlling the feeding accuracy of shredded tobacco leaves. Background technique [0002] In the process of shredded tobacco leaves, the control of precision error, accuracy and uniformity of flavoring and feeding is very important. In the prior art, a proportional-integral-derivative controller (Proportion Integration Differentiation, PID controller) is usually used to realize the control. The control of feeding accuracy error. [0003] The PID controller consists of a proportional unit P, an integral unit I and a differential unit D. The proportional unit P determines the proportional coefficient Kp, the integral unit I determines the integral coefficient Ki, and the differential unit D determines the differential coefficient Kd. In the prior art, a PID controller whose proportional coefficient K...
