Abstract :
The plant is a web transport system with winder and unwinder. Due to a wide-range variation of the radius and inertia of the rollers the system dynamics change considerably. Two different control strategies for web tension and linear transport velocity are presented. The first is an H∞ robust control strategy with varying gains based on a particularity of the plant. The second is an LPV control strategy with smooth scheduling of controllers synthesized for different operating points. The quadratic stability and the quadratic performance of the closed loop system are analyzed. The LPV control strategy gives better results on an experimental setup, for the rejection of the disturbances introduced by velocity variations
