Abstract

To solve the jitter problem of a servo system at low speed

the repetitive control method is studied to check the non linear disturbances such as motor moment fluctuation for improving the stability of low speed. After analyzing the reason of motor moment fluctuation

the theoretical model and quantity of the fluctuation caused by the motor's alveolus effect are discussed

and some experiments are made in the practical model system. The results show that the theoretical analysis is correct

and the fluctuation is periodical. The repetitive control law is introduced to check the periodical fluctuation. The design method of this controller and the control system are also discussed. The sine tracking experiments for the speed loop with repetitive controller were conducted. The results show that the repetitive control compensates the system's dead zone very well at low speed or zero crossing

and the maximum tracking error is 0.72″.
