An automated cooperative transfer method based on "light-field" for multiple automated guided vehicles (AGVs) is proposed to address the coordinated transfer of large aircraft sections. Utilizing laser measurement and control strategies, the method aims to enhance assembly efficiency and precision in aircraft manufacturing. First, a workspace measuring and positioning system (wMPS) is used to acquire real-time position and orientation data of each AGV, and a kinematic model of the transfer system is established to determine motion error. Next, combining fuzzy control with PID control, a fuzzy PID control algorithm adaptable to complex industrial environments is designed to adjust AGV cooperative motion errors in real-time, ensuring high-precision coordinated transfer. Experimental results indicate that the fuzzy PID control significantly improves the motion accuracy and load balance of the multi-AGV system under both unloaded and loaded conditions. Compared to open-loop control, the closed-loop approach maintains error within ± 10 mm, reduces the average load on positioning actuators by over 30%, and limits the maximum load to within ± 300 N. Additionally, dynamic adjustments of transfer tooling during the entire process effectively prevent potential section damage due to excessive force. This study provides technical support for the construction of flexible assembly lines for domestically produced large aircraft, showcasing substantial application value and potential for broader adoption.
