Abstract

A multivariable control system of rod bar rolling has been developed. This system consists of two parts: dynamic control (automatic gauge control and free tension control) and set-up. A set-up method of roll revolution speed for tension rolling is presented. The change of some load parameter is detected when each stand finishes rolling, and the roll revolution speed in the next bar is acquired by fuzzy inference. The fuzzy inference also adjusts control gain based on the stability of the load parameter, and avoids the miss operation
