Abstract :
A sufficient condition for the robust stability of systems with structured uncertainty is derived. The upper bounds measured by the H∞-norm for the sensitivity function and the closed-loop transfer function of the system are also given. These upper bounds may be used to test the stability of a system with complex structured uncertainties, as is shown in an example
