improve the disturbance attenuation characteristics of conventional repetitive control systems. Yamada et al. proposed a design method of multi-period repetitive controllers to attenuate widefrequency disturbances based on the idea of changing time-delay. Steinbuch proposed a design method of multi-period repetitive controllers for systems with uncertain period time. In this way, several design methods for multi-period repetitive controllers have been proposed. However, the parametrization of all stabilizing multi-period repetitive controllers has not been considered yet. In this paper, we propose the parametrization of all stabilizing multi-period repetitive controllers. Next, we present a design method of multi-period repetitive controllers using the obtained parametrization.

repetitive controllers for timedelay systems using the fusion of the structure of repetitive controllers and the factorization of time-delay plant into the time-delay part and the rational function part. A design method of stabilizing modified repetitive controllers using the obtained parametrization is presented. Finally, a numerical example is illustrated to show the effectiveness of the obtained parametrization.

modified repetitive controllers for non-minimum 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 by Youla et al. and Vidyasagar. The parametrization of all stabilizing controllers includes a free parameter, which is stable. That is, stabilizing repetitive controllers for non-minimum phase systems can be designed using the free parameter in the parametrization by Youla et al. and Vidyasagar. Using this idea, we obtain the parametrization of all stabilizing modified repetitive controllers for non-minimum phase systems. Next, a numerical example is illustrated to show the effectiveness of the proposed parametrization.

control, robust control using phase information and the parametrization of all proper stabilizing controllers for minimum phase strictly proper system. The parallel compensation technique is used so as to expand applicable plant of simple adaptive control and robust control using phase information. However the relationship between controllers that is obtained using parallel compensation technique and the parametrization of all stabilizing controllers have never considered. In the present paper, we consider this problem and give the necessary and sufficient condition that the class of controllers that is obtained using parallel compensation technique equal to that of controllers for the plant.

systems. The parametrization of all causal stabilizing repetitive controllers was first studied by Hara and Yamamoto. Katoh and Funahashi give the parametrization for the class of all stabilizing repetitive controllers for minimum phase biproper plants by solving the Bezout equation explicitly. However, Katoh and Funahashi assumed the plant is asymptotically stable. Using parallel compensation technique, Yamada and Okuyama gave explicit parametrization of all repetitive controllers for minimum phase systems that is not necessarily stable. We expand the result by Yamada and Okuyama and give the parametrization of all causal stabilizing controllers for certain class of non-minimum phase systems. Finally, a numerical example is used to illustrate the effectiveness of the proposed method.

parametrization is simple and does not contain improper controllers, that is, this parametrization contains only proper stabilizing controllers. This parametrization is given using supplemental rational function to hold certain condition and asymptotically stable free-parameter. A characteristic of stabilizing controllers for minimum phase systems is clarified.
