Abstract :
Robust stabilization for SISO (single-input single-output) systems with linear-fractional parameter uncertainties is considered. Necessary and sufficient conditions for the existence of robust controllers are derived. Their structure and parametrization can be obtained from the corresponding Nevanlinna-Pick interpolation problems. This extends the previously known case of uncertain gain parameter
