The problem of robustness bound for parameter uncertain systems with LQ guaranteed cost controller is considered in this paper. A parameter dependent robustness bound for parameter uncertainties is derived. Then, an optimization problem of improving the robustness of parameter uncertain systems is proposed. And also, the responding optimization technique is given in the paper.
