In this paper, we examine the pole location of the feedback system composed of the nominal plant and the H-infinity central controller designed by the robust stability-degree assignment. Namely, the exact pole location at gamma = infinity and the behavior near the infimum of gamma are clarified where gamma is the upper bound of the H-infinity norm constraint. The original design goal is to stabilize the plant against additive perturbations with the regional pole placement condition Re s < - , and the design problem is reduced to the one-block H-infinity control problem.
