This paper presents a new design method of discrete adaptive control system for nonminimum phase plants with unknown dead time.In the proposed method an adaptive control is carried out using a controller designed by a certain decomposed representation of the unknown plant.In this paper the two cases are considered regarding the dead time of the plant. First, we consider the case where is no a priori knowledge regarding the dead time of the plant. Next, the case where the approximate value of the dead time is known is described.Moreover, the connection between the proposed method and ordinary model reference adaptive control or adaptive pole assignment is clarified.Finally, the results of computer simulation of adaptive control applied to stable nonminimum phase plants with and without dead time are included to illustrate the effectiveness of the proposed method.
