The paper aims to control the single-degree-of-freedom packaging pallet conveyor with the fuzzy PID me-chanical control technology to achieve high efficiency and accuracy in actual factory pallet conveying. According to the high accuracy of the fuzzy PID control principle, the pallet transportation system with gear and rack as the main mechanical transmission mode was reasonably planned and compared with related traditional control systems. According to the different input values of membership degree, the movement path of its handling system was reasonably planned. Finally, the evaluation mechanism of the model was constructed by establishing effective test points for analysis. The high precision of the control system was verified by theoretical model and simulation demonstration. The precision error was -1.8 mm to 2 mm by simulation. By using the fuzzy PID control scheme, the overall control of the high precision mechanical conveying pallet system is effectively realized, which provides the research foundation for the good operation and algorithm optimization of related mechanical equipment.
