The traditional closed-loop subdivision method does not deal with the higher harmonics,which makes the sine and cosine encoder have poor stability in the case of strong harmonic interference and affects the accuracy of motion control.In this paper,a closed-loop subdivision strategy based on Kalman filter is studied to obtain stable subdivision signals,and the speed measurement method of the whole speed range of the system is improved and optimized.The simulation results show that the proposed method can effec-tively suppress the harmonics,improve the quality of subdivision signal,and effectively improve the speed measurement effect.Meet the requirements of high precision control.
