A new planetary gear using plastic gear and control system for photo-conductor (PC) drum drive in production printing is proposed. In order to obtain high image quality at low cost, driving technology using plastic gear to keep the PC velocity constant is needed. A feedback (FB) and feedforward (FF) controller is adapted to achieve ever higher performance. This paper proposed a new FF control strategy for reducing the periodic disturbance that is caused by transmission error of the planetary gears. The proposed control strategy reject the periodic disturbance based on switching scheme and open-loop observer. The advantage of proposed method is that periodic disturbance can be rejected without sacrifice of feedback performance. An experiment on prototype is carried out to verify the control performance. The experiment show that 90[%] periodic disturbance is reduced by the proposed control algorithm.
