摘要
介绍利用 PLC 高速计数器构成物料小车定位控制系统,采用最佳曲线拟合与脉冲控制相结合的控制方法对物料小车进行行走定位控制,实际运行中小车的定位精度可达±0.1mm 以内。
A orientation control system for the conveyer system is introduced in this paper. The system consists of the PLC high-speed counter. The orientation control method which combines the optimum curve fitting with the pulse control is implemented in the conveyer orientation control system. The result of practical operation shows that the accuracy of orientation control reaches ±0.1mm.
