ROBUST EXPONENTIAL STABILITY CONTROL FOR A CLASS OF NONLINEAR COMPLEX SYSTEMS
The paper addresses the problem of designing decentralized
robust controllers for a class of interconnected nonlinear
systems with uncertainties to guarantee the prescribed decay
rate of exponential stability for closed-loop uncertain systems.
The uncertainties, possibly nonlinear, can appear both in the
subsystems as well as in their interconnections. No matching
conditions or other similar constraints are required to model
the complex uncertain system. The design of governor controllers
for a three-machine power system verifies the proposed approach.
