Structured interpolation and robust control
Hari Bercovici, Ciprian Foiaş, Allen Tannenbaum · 1990
The authors extend their previous work on the spectral commutant lifting theorem to the case of structured singular values which appear in certain problems in control theory. They also give a new characterization of the structured singular value and formulate and prove a structured version of the matrix Nevanlinna-Pick theorem.>
