N2 - In motion control systems, disturbance suppression control is necessary to realize high precision control. Conventionally, control methods are designed on the basis of temporal dynamics. However, most disturbances are generated and related to moving conditions and actuator structures. In this paper, circle systems such as circle movements and structures are modeled, and a circle disturbance observer is proposed to suppress circle disturbances generated by the circle systems. The proposed method is designed by considering the spatial periodicity of the circle systems. It can reduce necessary estimated disturbances to memorize on the basis of the spatial periodicity. In order to compare the proposed method with a disturbance observer, simulations were conducted. The validity of the proposed method was confirmed by the experiments.
