纸机分部传动系统速差及电枢电流测量系统的研制

The development of speed-difference and armature current measuring system in paper-making machines' sectional drive system

速差控制是纸机分部传动系统自动化的关键 .提出用 5 1系列单片机 8XC5 1FA的PCA功能模块实现对传动速度、相邻级间速差以及电机电枢电流的高速高精度测量 .

The speed-difference control is critical for the automation of paper-making machines' sectional drive system. In this paper we use PCA function unit of 8XC51FA which is one of the mcs-51 one chip microcomputer series to measure drive speed,speed difference and armature electric current quickly and highly precisely.
