This paper deals with the control system design and simulation of the multivariable control system for bar and wire rod rolling. The control objective in the rolling is to maintain the interstand tension and output height and width of bar and wire rod product as prescribed. In this paper, we take a modern control theory approach to cope with those rolling systems. Based on the optimal regulator theory, a simultaneous control system of tension control and Gauge Meter AGC (automatic gauge control of exit height) is introduced. The control law is implemented by the output vector feedback and the partial state vector feedback. To evaluate the control performance, step responses due to input diameter and input temperature change are computed on a 4-stand tandem model mill. From the computed results,the validity of the present control system is confirmed.
