A state-space method for computing upper bounds for the peak of the st
ructured singular value over frequency for both real and complex uncer
tainties is presented. These bounds are based on the positivity and Po
pov criteria for one-sided, sector-bounded and for norm-bounded, block
-structured linear uncertainty, These criteria are restated and used t
o derive upper bounds for the peak structured singular value by equati
ng the feasibility of a linear matrix inequality which involves a plan
t state-space realization to the strict positive realness of a transfe
r function. Numerical examples are given to illustrate these upper bou
