| Research Abstract |
The modified repetitive control system is a type of servomechanism for periodic reference input. Even if the plant does not include a time delay, the transfer functions from both the reference input and the disturbance of the output of the modified repetitive control system generally have an infinite number of poles, and for this reason it is difficult to settle the input-output and the disturbance attenuation characteristics of a modified repetitive control system. From a practical point of view, the input--output and the disturbance attenuation characteristics of a control system need to be settled easily, and thus, it is desirable that the transfer functions from both the reference input and the disturbance to the output have a finite number of poles. In order to easily specify the input--output and the disturbance attenuation characteristics, we propose the concept of a simple repetitive control system in which the controller works as a stabilizing modified repetitive controller and the transfer functions to the output from both the reference input and the disturbance have a finite number of poles. In addition, the parameterization of all stabilizing simple repetitive controllers is clarified.
