DIGITAL OPTIMAL CONTROL OF MULTI-STAND ROLLING MILLS WITH MEASUREMENT AND INPUT DELAYS

DIGITAL OPTIMAL CONTROL OF MULTI-STAND ROLLING MILLS WITH MEASUREMENT AND INPUT DELAYS

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 measurement and control input are tak...
