Design of Rectifying Controller Based on Fuzzy PID Control Strategy

Strip offset can cause registration errors, resulting in a large amount of waste during the printing process. In order to achieve precise control of the running track, this paper designs a correction system controller based on fuzzy PID control strategy. Firstly, the basic principle of the belt transmission is analyzed, and the dynamic model of the belt movement is established. Secondly, The ultrasonic sensor is used as the detection device, SCM is used as the control core and the stepping motor is used as the actuator. Thirdly, a correction system control method based on fuzzy PID control strategy is proposed, and the control system software is developed. Experiments show that the correction controller can realize rectifying control of various types of printing materials and is suitable for a variety of high-end printing equipment.
