Abstract :
It is shown how bounds on the sensitivity function and the complementary sensitivity function which are not simultaneously achievable by any stabilizing controller can be computed by means of the H∞ approach. This allows evaluation of a given synthesis in terms of its distance from nonachievable specifications and provides information about design tradeoffs
