Abstract:
This work investigates an application of interpolating gain-scheduling (IGS) control for a structural acoustic isolation problem. The dynamics of the system under consideration are highly sensitive to changes in the temperature. For this purpose, linear time invariant H2 dynamic output feedback controllers are designed for different temperature conditions. Afterward, these controllers are interpolated to provide a global discrete-time LPV controller. The closed-loop stability is a posteriori guaranteed using recent less conservative analyses that consider bounds on the rate of variation of the temperature. Copyright © 2007 IFAC.
