A tracking problem for linear uncertain systems is considered. A robust feedback controller is designed such that the closed loop system is quadratically stable and its output tracks a command step input. One such controller is obtained by applying the quadratic stabilization method from the viewpoint of Inverse LQ problem. Attractive features of the design method proposed lie in its simplicity in several senses from the practical viewpoint.
