Abstract: Multi-period repetitive controllers were proposed by Gotou et al., in order to improve the disturbance attenuation characteristic of modified repetitive control systems. Recently, the parametrization of all stabilizing multi-period repetitive controllers was obtained. Since the parametrization of all stabilizing multi-period repetitive controllers was obtained, we can express previous studies of multi-period repetitive controllers in a uniform manner. In addition, a multi-period repetitive controller can be designed systematically. However, an application of control system using the parametrization of all stabilizing multi-period repetitive controllers has not examined yet. In this paper, we show the effectiveness of the control system using the parametrization of all stabilizing multi-period repetitive controllers for reduction of rotational unevenness in motors.
