ROBUST ADAPTIVE CONTROL FOR A CLASS OF COMPLEX SYSTEMS

Vojtech Veselý

   The paper addresses the problem of robust adaptive decentralized control design for nonlinear and linear interconnected complex dynamical systems with uncertainties. A new class of adaptive robust continuous algorithm is proposed to guarantee stability of uncertain nonlinear and linear systems without matching conditions. These uncertainties may appear both in each subsystem as system and input uncertainties and in the interconnections. No statistical information about the uncertainty is imposed. The proposed theoretical approach is verified by two examples. The design of robust controllers and simulation results of both a three machine power system with a nonlinear model and a three vertical pendulum with a linearized model without matching conditions verify the proposed theoretical analysis.
