Abstract

Repetitive control was applied to DC motor speed regulation in a scan device to reject the motor cogging torque. A discrete time prototype repetitive controller was designed and integrated into an existing feedback loop using the plug-in concept to reject the approximately periodic cogging torque under a constant reference speed. System identification was conducted to obtain the linear plant model. With the implemented repetitive controller, the periodic speed error was attenuated by near 75%. Also, a robustness criterion was developed to guarantee successful implementation on real systems.
