profile measurements for world class quality

first requirement for a hot-strip mill gauging system is to provide a fast low-noise centerline thickness output for automatic gauge control (AGC) purposes. This is achieved by averaging each 5 ms profile across a section of the center portion, 100mm typically being used. A running average is made of the last three samples before making the output.

Automatic generation control Wikipedia

In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load.Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary.

Optimum Gain Design for Hydraulic Screw-Down AGC

The problems treated here are gaugemeter AGC and absolute AGC which has a zero in its transfer function. Applying the optimum regulator, the Riccati equation with compatibility conditions are analytically solved to find the optimum gains. As a result, these gains are proved to be a function of a plastic coefficient of the rolling material, mill
