Abstract :
The D-stability robustness in a specified sector of uncertain linear systems is transformed into a nonsingularity problem of a family of parameterized matrices and then the D-stability bounds keeping the poles of the systems in the sector in left-half plane are derived and the stability bounds are also given. These bounds do not imply quadratic stability or quadratic D-stability and are approximated to their practical values and they are the actual robust stability and D stability bounds indeed when there is only one perturbed parameter
