Abstract

The authors examine a variety of novel techniques for assessing the stability robustness of linear multivariable feedback control systems. The conservatism of various robustness tests is discussed. A nonconservative measure of robustness called the structured singular value test is introduced. An interconnected structure that applies to real and complex stability tests is demonstrated. Some remarks are made concerning the computability of various tests. It is concluded that structured singular values are less conservative than singular values, but are still conservative when compared to algorithms that attempt to compute an exact stability margin for a combination of parameter variations.<>
