Abstract-- In this paper, we consider a controller failure time
analysis problem for a class of symmetric linear time-invariant
(LTI) systems controlled by a pre-designed symmetric static
output feedback. We assume that the controller fails from time
to time due to physical or purposeful reason, and analyze
stability and H disturbance attenuation properties for the
entire system. Our objective is to find conditions concerning
