Abstract: Under the background of cloth process for a pellet plant, as to the incorrect positioning and asymmetric cloth of the plant’s cloth in cloth link, a fuzzy control algorithm based on PLC is proposed, with combining the ultrasonic level meter and feedback information of laser distance measuring instrument, which can solve the lack of cloth system effectively. The use of PC configuration interface can achieve remote monitor of cloth process to improve the automation level of this plant and the work condition. During the operation, the proposed system not only can determine material requirements of the orestorage and achieve the accurate positioning of the dumper, but also can reduce the working strength for operators.
