Digital optimal control of multi-stand rolling mills with measurement and input delays

Abstract

In this paper, the problem of designing an optimal control algorithm for rolling processes is addressed. Deriving a mathematical model for a general class of rolling mills, the optimal control problem is defined. In the design procedure, time delays in thickness measurment and control input are taken into account. The proposed strategy significantly improves the results of previous investigations from practical point of view. Simulation results are also studied to highlight the effictiveness of the method. © School of Engineering, Taylor's University.
