Tension analysis and decentralized control for tobacco laminating production system;

烟泊复合生产过程中的张力分析及分布式控制

The stability tension of laminating production system is the key to successful operations and required product quality.

复合生产过程中的张力稳定控制是保证产品质量的关键技术之一,通过对烟泊复合生产过程的分析,提出三段式张力控制方法,分别对放卷、收卷、及中间传输部分的张力进行控制;对放卷张力控制采用磁粉制动器作为执行机构,而收卷和中间传输部分张力控制以直流电机作为执行机构,对各部分张力控制提出了相应的PI控制算法,有效减小了各部分之间张力的耦合与影响;构建了生产线张力控制的PLC网络,以SIEMENS公司的S7-300可编程序控制器为控制器,以触摸屏为人机界面,通过MPI网络实现对生产线的恒张力控制;实际生产情况表明,该系统运行稳定,控制精度符合设计要求。
