In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for the strip exit …
maximum rolling speed of a cold or foil mill, 8 meters of strip is produced. It is easy to see why Automatic Gauge Control (AGC) is an essential component of modern rolling mills. Comprehensive AGC algorithms incorporate readings from dozens of sensors around the mill. Some of the key AGC input parameters are speed and tension. (See Figure 1)

flatness information, and is helpful for rolling mill to give full play to the flatness control, so as to improve the accuracy of flatness control[11]. The actuator efficiency for flatness control is the amount of flatness change under unit volume regulation[1]. For the 1250 single stand 6-H reversible UCM cold mill, there are 23 measurement points
Menghui and his colleagues in 2007 in research about control in hydraulic AGC of cold rolling mill used the cascade predictive control by the combination of PID control for the HAGC and dynamic matrix control for the inner loop of the screw-down servo system. This method can hardly solve the problem of gaining the step response of the whole HAGC.

Rolling mills are not a standard machine tool, nor are they built for stock. They are designed and built-to-order to specifically accomplish an end product or process. At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills and blooming mills.

types of Automatic Gauge Control (AGC) methods have been developed for hot or cold mill processes. The Brit-ish Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3].

An automatic gauge control (AGC) system for rolling mills utilizes the output thickness as the feedback variable. Usually the thickness sensor is place too far from the roll-gap, and this causes a time delay in the feedback control loop which also depends on the strip speed.
