| 摘 要： | 针对工业生产中一些大行程、高精度定位控制要求,提出基于带型磁栅尺和PLC的位置闭环控制系统。采用西门子S7-200 PLC,实时捕捉磁栅尺的高速脉冲,实现了大行程位置闭环自动定位控制,并应用于塑钢型材锯切中心控制系统,以较低的成本,解决了传统步进电机开环控制带来的精度问题,大大降低了精确定位控制门槛,具有很强的实际应用价值。 |
| 关 键 词： | PLC 磁栅尺 位置闭环 |

| Abstract: | In this paper,focus on the requirements of large travel,high accuracy positioning control,a position closed-loop positioning control system is proposed based on magnetic railings ruler and PLC.Using high-speed counter instruction,capture the high speed pulses of magnetic railings ruler in real time to realize large travel automatic positioning control.This method has been applied to the sawing center of PVC profile cutting.The accuracy problems of stepping motor open-loop control in positioning control system are solved with lower cost,greatly reduced the technology threshold,and has a strong practical value. |
| Keywords: | PLC magnetic railings ruler position closed-loop |
