摘　　要：针对目前在线运行的CPC(center position control)自动对中控制系统存在响应速度慢、容易受到现场干扰以及检测精度低的问题,设计开发了一种新的高性能CPC自动对中控制系统;该系统主要是采用电磁感应原理检测带钢的位置,然后采用电子电路对控制对象的位置信号进行放大、滤波,再经过STM32微控制器、控制柜、液压控制等单元调整导辊位置来实现对控制对象的对中控制;整个电路系统的检测和控制精度为1mm,并且信号线性度以及稳定性好,提高了产品的可靠性。According to the present online operation of CPC （center position control） automatic control of the system response speed is slow, vulnerable to the interference on spot and of low precision, thus designing and developing a high performance of CPC auto control system. The system that detects strip position is mainly using the electromagnetic induction principle, and then use electronic circuit to control the position of the object signal amplifying, filtering, then adjust the position of guide roller to control the object with STM32 microcontroller, control cabinet and the hydraulic control unit. The whole circuit system of detection and control precision can reach 1 mm, signal linearity and stability is also very good, greatly improve the reliability of products. The product has been invested in the industrial production, and the effect is better.
