The robustness bound for the pole-assignment of uncertain systems with structured perturbations is considered. Based on the Lyapunov stability theorem and on properties of the matrix measure function, the condition for robustly assigning system poles to a specified region is derived. The bound for robust pole-assignment is used as a measure for control system design to attain certain specified performance requirements. The nonlinear programming is used to search for an optimal matrix Q in the Lyapunov equation and an optimal feedback gain matrix F for improving the robustness bound. Some examples are presented to illustrate applications of the proposed techniques.
