摘要:无轴传动技术在凹版印刷上得到的广泛的应用。本文以凹印机套准系统的多电机同步问题为研究对象,采用基于补偿原理的模糊PID的同步控制算法,并搭建了以西门子S7-300 PLC为控制器的主从式同步控制系统,来进行多电机同步控制的研究。仿真表明,这种方案鲁棒性、快速性优良、动态过程同步误差小,能够较好地满足被控对象对高精度同步控制的要求。

Abstract: The shaftless drive technology has been widely applied on gravure printing. In this paper ,the gravure printer registration system’s multi-motor synchronization problem is regarded as the research object..For the purpose of research of multi-motor synchronization control ,the algorithm of Fuzzy-PID synchronization based pensation principle is adopted and the Master-slave synchronization system based on SIMENS S7-300 PLC was designed. The simulation results indicate that the proposed method has stong noise immunity and robustness and the rapidity is good and dynamical synchronous error is low .So this control method can satisfy the demands of the controlled subject for the high precision applicatios.
