Abstract
Web handling systems are complex systems requiring more and more effective control laws to deal with very high speed. Some interesting results have been recently obtained with H2 or Hinfin multivariable control strategies. However such solutions have the drawback to lead to centralized controller difficult to implement on large-scale systems. The use of structured controller is therefore necessary. Considering a 3 motors Web handling system, a suboptimal H 2 controller, internally structured is proposed. Neither centralized nor decentralized, it is based on a state feedback with overlapping two-by-two cooperative local observers. It is shown that such structured controller offers enough degrees of freedom to be as efficient as the centralized controller. The synthesis is made by solving two structured static controller design problems using a dilated LMI algorithm
