This paper deals with a design problem of a memoryless robust controller which achieves performance robustness together with robust stability for linear uncetain discrete-time systems with state delays. The performance robustness under consideration means that comparing the transient behavior of the uncertain system with a desired one generated by the nominal system, the deterioration of control performance is suppressed and at the same time excessive control input is avoided. In this approach, the control law consists of a control input desibned by using the nominal system and an additive compensation input. In this paper, we show that sufficient conditions for the existence of the compensation input are given in terms of linear matrix inequalities(LMIs).
