两种液压位置控制技术的分析与对比

Analysis and Comparison of Two Hydraulic Position Control Technologies

以宝钢三热轧1880mm主轧线典型设备为例,对两种液压位置控制方式——电磁阀控制方式、电液伺服控制方式进行分析与对比,重点阐述了两者位置控制的基本原理(前者主要采用CPC模块进行控制,后者主要采用APC模块进行控制),从中总结出各自的优势及劣势,并针对现场出现的问题提出改进设想和建议。

Taking the typical devices of Baosteel No.3 Hot Rolling 1 880mm (main rolling line) for instance,this paper analysed and compared the two hydraulic position control technologies:the solenoid valve position control and the electro-hydraulic servo control. It also focused on the two basic principles of the position control (the first mainly uses the CPC subroutine,the second mainly uses the APC subroutine). The paper summed up the advantages and disadvantages of the two principles respectively. Some ideas and...
