The structured singular value (SSV) has been used in recent studies of the robust stability of feedback systems subject to real-parameter variations. An attempt is made to summarize the results obtained when some new upper bounds on the SSV for real parameters were used in two studies of flight control systems. The perturbation structure for higher rank perturbations is discussed and the issue of lower bounds for the SSV in the real-parameter problem is considered. A new theoretical result relevant to lower bounds in a special case is given.
