Objective To study the shaftless drive technology of gravure printing machine. Methods Based on intelligent control technology, combined with the nonlinear characteristics of multi-axis synchronization control system, fuzzy PID controller with optional function parameters was used to improve the multi-motor system. A simulation platform was built by Matlab/Simulink, a multi-motor system model with master-slave synchronization control was established, and simulation was performed for this system. Results Comparison of the results of PID control and fuzzy PID control indicated that fuzzy PID control system could control the initial overshoot phenomenon, and quickly reach a steady state, which improved the robustness and rapidity of the system. Conclusion Fuzzy PID control met the requirements for fast response and high accuracy of permanent magnet synchronous motor.
