Robust Controllers for Large-Scale Interconnected Systems: Applications to Web Processing Machines Conference Paper uri icon


  • © 2006, Birkhäuser Boston. Decentralized control of large-scale systems with uncertain, unmatched interconnections is considered. A stable decentralized adaptive controller is proposed for both linear and nonlinear interconnections. Sufficient conditions under which the overall large-scale system is stable are developed; results from algebraic Riccati equations are used to develop these conditions. The choice of the class of large-scale systems considered is directly motivated by control of web processing machines used in processing of materials. A large experimental web platform is considered for experimental study of the proposed decentralized adaptive controller and its comparison to a decentralized PI controller, which is widely used in the web processing industry. Extensive experiments were conducted; a representative sample of the experiments is presented and discussed.
