Decentralized robust controller for exponential stability of uncertain systems with output feedback

摘要

The paper addresses the problem of design of robust decentralized controllers with output feedback for interconnected linear systems with uncertainties. A new class of robust continuous-time and discrete-time controllers is proposed to guarantee exponential stability of uncertain linear systems without matching conditions. The uncertainties possibly nonlinear can appear both in the subsystems and in the interconnections between them. The proposed algorithm is applied to 6th order system model comprising two subsystems with decentralized controller.
