Abstract :
In an aluminium strip processing line, the main concern is to control independently velocity and tension. This paper deals with two control systems applied to a basic unwinder-rewinder system: the first one is based on classic PI controllers including specific compensations. The second is a LQG control. Simulations demonstrate the effectiveness of both solutions.
