摘要
在进行控制系统设计时,考虑到成本因素,经常会在备用设备中采用共用电源,本文通过酒钢中厚板轧机的AGC系统中互备伺服阀采用的共用电源带来的故障,阐述了共用电源对系统运行带来的潜在隐患。
In control system design, taking into account the cost, it often used in sharing power in back-up devices. This article describes the system running the potential risk, base on servo valve sharing power of JISCO plate mill AGC system hast brought fault.
