DECENTRALIZED ROBUST EXPONENTIAL STABILITY OF NONLINEAR SYSTEMS WITH OUTPUT FEEDBACK
Vojtech Veselư
The paper addresses the design of decentralized
robust controllers with output feedback for a class of
interconnected nonlinear systems with uncertainties which have
to guarantee a prescribed exponential stability decay rate
of the closed-loop. The uncertainties, in general nonlinear, can
appear both in the subsystems as well as in their interconnections. No
matching conditions or other similar constraints are to be considered
in the complex uncertain system model. The proposed approach has been
verified on governor controllers for a three-machine power system.
