Application and Research of New Monitor AGC in Hot Strip Mill

摘要

A Monitor AGC control system is applied to a hot strip mill in a steel plant, due to some irrationality gain factors and the hysteresis of the Monitor AGC control output, the strip thickness deviation is large. This paper designs a new type Monitor AGC that includes two control methods: Integral type Monitor AGC and Smith's method Monitor AGC, they are able to select alternately. The experimental results show that the effect of Integral type Monitor AGC and Smith's method Monitor AGC is obvious, and the accuracy of thickness control is obviously improved.
