Abstract: Based on the analysis of the working principle of rectification and the key factors affecting rectification control accuracy, the CCD (Charge Coupled Device) linear array image sensor is selected as the detecting element in this paper. Then, the actuator is made up of the stepper motor, the worm\|and\|wheel gear and the correction roller. Besides, a compound control strategy of FUZZY\|PID is introduced in the controller. Finally, the rectification control system for tape winding is established. According to the experimental verification, the rectification accuracy fully meets the requirements of winding process, thus realizing the rectification automation.
