| 摘 要： | 国内某1500热连轧精轧液压自动厚度控制系统,采用了专用于复杂的闭环控制和高速数学运算的西门子SIMATIC TDC多处理器控制器.通过反馈模型(GM-AGC)、油膜厚度补偿、活套补偿、宽度补偿(指对轧机的弹性变形系数的修正)、弯辊力补偿,X-射线厚度偏差监控等功能来控制带钢厚度.此外,还具有便于同一批号的下一块钢穿带的压下及咬入速度的复归功能.此AGC系统为串联双环系统,内环APC-直运行,外环AGC设定值作为APC附加设定,实现AGC功能.该系统稳定性、操作性好,响应速度快,控制精度高. |

| Abstract: | Siemens Simatic TDC multi-processor controller is used in hydraulic automatic gauge control system of a certain 1500 hot strip mill,it is applied in complex closed loop control and high speed mathematics calculation technically.The strip thickness is adjusted by GM-AGC,oil compensation,looper compensation,width compensation,bend compensation and X-RAY monitor.Otherwise,the return function provides advantage for screw down and speed of the same batch next strip.The AGC is double loop system,in-loop APC is al... |
