state feedback controller design for lateral motion of a hot strip with input delay and actuator saturation

Abstract

Lateral motion of a strip is a problem during hot rolling process which results in quality deterioration of products. Excessive lateral motion of a strip is one of factors which eventually resulting in suspension of overall rolling process. That is the reason why lots of researches have been focused on the control problem of lateral motion. In this paper, using the linear mathematical model of lateral motion, a feedback law considering stability and disturbance tolerance of the closed loop system with actuator saturation and input delay is proposed. Numerical results show the efficiency of proposed algorithm for reducing lateral motion of a strip.
