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.application/pdf414351 bytesapplication/pdfen-USjournal article10.1109/MWSCAS.1994.519059http://ntur.lib.ntu.edu.tw/bitstream/246246/2007041910032408/1/00519059.pdf
