In the present paper, we give the parametrization of all stabilizing repetitive controllers for nonminimum phase systems. The basic idea to obtain the parametrization of all repetitive controllers for nonminimum phase systems is very simple. If the repetitive controller stabilizes the plant, then the repetitive controller must be included in the class of all stabilizing controllers for the plant. The parametrization of all stabilizing controllers for the plant, which is not necessarily repetitive controllers, are obtained using the parametrization of all stabilizing controllers for the plant by Youla et al. and Vidyasagar. The parametrization of all stabilizing controllers include free parameter, which is asymptotically stable. That is, stabilizing repetitive controllers for the nonminimum phase systems can be designed using the freeparameter in the parametrization. Using this idea, we obtain the parametrization of all stabilizing repetitive controllers for the non-minimum phase systems. Next, a design method of free parameter in the parametrization of all stabilizing repetitive controllers for the nonminimum phase systems is presented
