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

The present application provides a deviation correction control method, a controller and a deviation correction control system, which are applied to a preset linear equation of a fitting curve. The actual position value of the material, and obtain the actual voltage value generated by the A / D conversion board according to the actual position value, and substitute the actual position value into the linear equation of the fitting curve to obtain the voltage prediction corresponding to the actual position value value, when the actual voltage value is different from the predicted voltage value, the position correction value corresponding to the actual position value is determined according to the actual voltage value and the predicted voltage value, and then the servo drive is triggered according to the position The deviation correction value drives the motor, so as to realize the deviation correction control of the coil.
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...
