Abstract:
New points of view to the problems concerning the decentralized control of a class of large-scale systems with relevant subsystems interactions are presented in the paper. The problems are transformed into enhanced design conditions through slack matrices until global asymptotic stability of the complete system is pursued using Lyapunov approach. As results, a sufficient condition for the existence is formulated in terms of linear matrix inequalities while the impact of interconnection uncertainties is minimized using Hinf approach. The decentralized controllers proved to globally stabilize the system, both in noiseless and noisy conditions.
