EPC系统爬行现象的研究与对策

Creeping Phenomenon's Research and Solution of EPC System

显著的降低废品,提高产品质量,加快整个机组生产过程的生产率和速度是采用EPC系统可达到的直接效果,因此合适的边导控制系统,运动中的带钢侧向位置控制,是钢铁行业生产制造过程中的基本要求。本文针对影响控制性能较严重的爬行现象,建立了纠偏系统动力机构的状态方程模型,通过仿真工具,研究纠偏系统执行元件产生爬行现象的原因,详细分析了系统连接刚度、摩擦状态、液压缸有效作用面积等对爬行的影响,并提出相应的改进措施。结果表明,改进措施能正确、可行、有效地缓解爬行现象。

Focusing on creeping phenomenon of EPC system which effects control capacity greatly, the state - space of active units of guiding system was established, through simulating tools, the reason of creeping phenomenon was tried to be found, elements which may cause creeping like connection rigidity, friction status, effective function area of cylinder were analyzed, improvement measure was gotten. Result shows that the measure is feasible and effective to eliminate creeping.
