Abstract :
A frequency domain analytical tool that verifies stability robustness for structured uncertainty consisting of real parameter variations is described. The method provides a nonconservative measure of the system´s stability margin. It utilizes a numerical technique based on homotopies to ensure that a global minimum has been found.
