Here we present our works. Section 1 is the introduction. The friction and moment fluctuation of the motor at low speed for the optoelectronic system are tested out which are shown in section 2. We introduce a repeat controller to the system to compensate the low-speed disturbances in section 3. Concerning the stability  a filter is added to the repeat controller. The experimental results are discussed in section 4. Not only the repeat control can overcome some low-speed-disturbances  but is more useful when tracking a periodic input signal.
