Abstract:
We present conditions, some necessary and some sufficient,
for robust stability and uniform robust stability of
uncertain linear time-invariant systems with linear
time-invariant uncertainties that are block-diagonal,
with known frequency-dependent norm bounds on the
diagonal blocks. Under
stronger assumptions on the frequency dependence of the
uncertainty bound, we obtain necessary and sufficient
conditions.
