Embodiment Construction
[0036] In the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. For example, the first chip and the second chip are only used to distinguish different chips, and their sequence is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order, and words such as "first" and "second" do not necessarily limit the difference.
[0037] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations or descriptions. Any embodiment or design described herein as "exemplary" or "for example" is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

The embodiment of the invention provides a copper foil production tension control method and system and a storage medium, and is applied to the technical field of copper foils. The method comprises the steps that a controller obtains a deviation value between copper foil tension and a tension threshold value; under the condition that the deviation value is greater than a first deviation threshold value, the controller conducts proportional differential operation on the deviation value according to a proportional differential operation function, and obtains the adjustment amount of the rotating speed; the rotating speed of the copper foil processing device is adjusted according to the adjustment amount, under the condition that the deviation value is less than or equal to a first deviation threshold value and greater than a second deviation threshold value, the controller conducts incomplete integration in the process of conducting proportional integral differential operation on the obtained deviation value, and obtains the first rotating speed adjustment amount; and the rotating speed of the copper foil processing device is adjusted according to the first rotating speed adjustment amount, so that the controller adopts proportional differential operation to improve the adjustment efficiency of the tension of the copper foil, and incomplete integration is carried out on the deviation value, so that the situation that the adjustment amount is too large and the adjustment amplitude of the tension of the copper foil is too large is avoided.
Description
technical field [0001] The present application relates to the field of control technology, in particular to a method, system and storage medium for controlling tension in copper foil production. Background technique [0002] In the copper foil production process, a copper foil surface treatment system needs to be applied. The copper foil surface treatment system includes a controller, a power unit and a copper foil treatment device. The copper foil processing device includes an unwinding device, a conductive roller, and a winding device. The copper foil surface treatment system makes the produced copper foil maintain a certain copper foil tension. After processing, the copper foil with copper foil tension can reach the performance indicators such as thickness, stretch and ductility of the copper foil required for production. Copper foil tension is the tensile force exerted on the copper foil by the copper foil processing device. Copper foil tension is determined by the rot...
