中文摘要：
目的针对凹版印刷机上的无轴传动技术进行研究。方法以智能控制技术为基础,结合多轴同步控制系统的非线性等特点,通过具有参数自选功能的模糊PID控制器,对多电机系统进行改进;通过Matlab/Simulink构建仿真平台,搭建主从同步控制的多电机系统模型,并对该系统进行仿真。结果通过PID控制和模糊PID控制的结果比较,模糊PID控制能控制系统初始时的超调现象,能更快达到稳定状态,使系统的鲁棒性和快速性得到提高。结论模糊PID控制很好的满足了永磁同步电机响应快、高精度的要求。
英文摘要：
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.
