Lateral Control of Roll-to-Roll System Using Fuzzy Control Logic and Vision Sensor
We report in this paper the control work of lateral displacement of a web that runs on a roll-to-roll system. The control system employs a displacement guide and a vision sensor. The vision sensor is used to detect the lateral displacement of a moving web and send a feedback signal to a controller. A fuzzy logic is developed and embedded in the controller. Experimental results are presented to evaluate the control logic and system.
