Decoupling control of automatic gauge control system in hot-rolling mills

It´s possible for different kinds of automatic gauge control (AGC) systems working simultaneously to impact and disturb each other while adjusting their moving directions. In order to implement a decoupling control, we modified the parameters and structure of the AGC system in a hot rolling mill. As a result, it was proved that theoretically, gauge meter type AGC system and monitoring AGC system could be independent of each other by computer simulation and mathematics models, namely, decoupling control of these two AGC systems was realized in the true sense.
