Abstract

This brief paper deals with the return difference function and the inverse optimal control problem for linear single-input discrete-time systems with a quadratic performance criterion. It is pointed out that there are essential differences with respect to the case of continuous-time systems. The effect of these differences on the stability margins and the sensitivity properties of optimal feedback discrete-time systems is analysed.
