是整个轧线系统中的关键部分之一,要求具有较好的系统 结构及系统的快速响应,保证位移精度等各项工艺要求。 位置控制是将被控对象调节到设定的位置,要求在短 的时间内,使被控对象完成定位动作,且符合技术要求 规定的位置精度要求。轧机压下控制根据位置控制指令,驱动压下装置来实 现。轧制计划事先存储在轧线计算机中,轧制时根据不 同的轧制要求,由计算机选择相应的轧制计划送往 SPC及APC 控制用 PLC,当接受新系统计算机来的轧制计划信 息后,首先自动更新当前压下控制和推床位置的设定值, 同时不断采集两者位置的实际值(反馈值),经 CPU 运算 后求出 △S 位置偏差值,根据期望的运动曲线不断刷新电 机的速度给定值,当 △S 进入定位精度范围内,电机速度 给定为零,实现系统 APC的位置控制。
