ROBUST EXPONENTIAL STABILITY CONTROL FOR A CLASS OF NONLINEAR COMPLEX SYSTEMS

Vojtech Veselý

   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.
