摘要:
A feedback control of a hot and/or cold rolling process by means of a process control system, which executes a predetermined rolling program containing the initial and final dimensions, material data, roll temperatures, etc., and has a master system for controlling the setpoint values of subordinate, preferably decoupled, individual control units for the variable functional variables of the individual roll stands, e.g. rolling force, rotational speed, screw-down position [setting], etc. The setpoint values of the control units are determined in a computational operation using model equations, in which prepared and statistically processed measured values of the process variables are substituted, with convergent adaptation of absolute parameters to the actual parameters. In the event of changes in the requirements of the rolling process, in particular in the event of a transition from manual to automatic operation, or of changes in the final thickness, and/or changes in temperature, a relative adaptation of the parameters is carried out on the basis of the set values used before the changes in requirements as initial values.
