A method of controlling tension in a material handling process. An error signal of the process is determined. The velocity analog value of the material is determined and an instantaneous integral gain is then determined according to the velocity analog value. A proportional gain is determined. The output of a controller is then adjusted according to the error signal, the instantaneous integral gain, and the proportional gain.
L'invention concerne un procédé de commande de la tension dans un processus de traitement de matériau, qui comporte les étapes consistant à déterminer un signal d'erreur ; à déterminer une valeur analogue à la vitesse du matériau ; à déterminer un gain intégré instantané selon la valeur analogue à la vitesse du matériau ; à déterminer un gain proportionnel ; et à régler ensuite le signal de sortie d'un organe de commande en fonction du signal d'erreur, du gain intégré instantané et du gain proportionnel.
