| Abstract: | In this paper, the problem of the stability robustness and the
performance sensitivity is investigated for systems under stable feedback structured
uncertainties both on the plant G and the feedback controller K simultaneously.
Sufficient conditions for the robust stability and the upper bounds for the sensitivity
function matrix and the closed-loop transfer function matrix are given in terms of
H∞-norms. The controller K does not need to be proper and stable, therefore the
results obtained here is of general sense. |
