  Weighted sensitivity minimization is studied within the framework of strongly
stabilizing (stable) H-infinity controller design for a class of infinite
dimensional systems. This problem has been solved by Ganesh and Pearson, [11],
for finite dimensional plants using Nevanlinna-Pick interpolation. We extend
their technique to a class of unstable time delay systems. Moreover, we
illustrate suboptimal solutions, and their robust implementation.
