Deviation rectification control method, controller and deviation rectification control system

Abstract

The invention provides a deviation rectification control method, a controller and a deviation rectification control system which are applied to a preset fitting curve linear equation. The fitting curve linear equation represents the corresponding relationship between the position value and the voltage value, obtains the practical position value, collected by a position sensor, of a coiled material and obtains the actual voltage value generated by an A / D conversion board according to the actual position value; the actual position value is substituted into the fitting curve linear equation, the predicated voltage value corresponding to the actual position value is obtained; the position deviation rectification value corresponding to the actual position value is obtained according to the actual voltage value and the predicated voltage value when the actual voltage value is different from the predicated voltage value; and a servo driver is triggered to drive a motor according to the position deviation rectification value, so that the deviation rectification control over the coiled material is achieved.

Description

technical field [0001] The present application relates to the technical field of detection control, in particular to a deviation correction control method, a controller and a deviation correction control system. Background technique [0002] Correction control is an important technology in process control. It is used in many coil processing industries such as packaging, printing, labeling, garments, and metal processing. The coils involved include plastics, cables, paper, textiles, etc. types of materials. The processing process of the coil includes the treatment of the coil itself, such as spraying, printing, die-cutting, lamination, and can also include the processing of the coil into finished products, such as processing into bags. [0003] Specifically, during coil processing, the coil needs to move in a fixed track to complete a series of processing processes. If the coil deviates during the transmission process, that is, the edge of the coil does not run neatly in the...

Problems solved by technology

[0003] Specifically, during coil processing, the coil needs to move in a fixed track to complete a series of processing processes. If the coil deviates during the transmission process, that is, the edge of the coil does not run neatly in the track, then It will cause errors in subsequent steps, resulting in waste of materials or shutdown adjustments
