Abstract :
The authors give a sufficient condition for the robust stability of systems with structured uncertainty. The upper bounds measured by the H∞-norm for the sensitivity function and the closed-loop transfer function of the system are also discussed. It is shown that the upper bounds for a certain performance index derived may be used to deal with the robust stability of the system with multiplicative and additive uncertainties at the same time, as illustrated in an example
