Design and experiment of multi-station automatic powder loading system based on fuzzy control

Abstract

Objective: In view of the technical problems such as low efficiency and difficult automatic control of the automatic powder production line for factory rice noodle production. Methods: This research proposed a multi-station automatic powder loading system based on fuzzy control, selecting the deviation E1 between the detected value of the powder height and the preset value, the deviation change rate EC1 and the deviation between the current position of the powder loading car and the position to be loaded. The absolute value E2 was used as the input variable, and the motor speed U1 and the opening degree of the bin door U2 of the powder loading system were used as the output variables. The working efficiency of the powder loading system was improved by adjusting the motor speed and the opening of the bin door of the powder loading system through fuzzy control rules. The control system was built on the Siemens S7-1200 PLC platform, and the field test was carried out. Results: The test showed that for the 6-station automatic powder loading and conveying production line, the operation efficiency of this control system was improved by 103.2% compared with the existing control system, and the output of each station per unit time was increased by 31.4%. Conclusion: The number of stations that the system can accommodate 4 points have been raised. The experiment can be used for reference in the design of the control system for realizing high efficiency and automation of the factory rice flour production line.
