Abstract
The robust stability of systems with parametric uncertainties, input delays, and output feedback controllers is analyzed in this paper. First, the stability condition of nominal systems is expressed in terms of the eigenvalues of a Hamiltonian matrix. Then, for the nominally stable uncertain systems, a new method based on structured singular value and linear fractional transformation techniques is proposed, so that the Lyapunov stability theory can be used to find a set of uncertain parameters within which the systems remain stable. Finally, it is remarked that the results can be extended to uncertain systems with multiple time delays.
