【Abstract】 The noise disturbance signals in CNC machine tool servo system electrical interfaces and components will reduce the tracking accuracy of servo feed system. The influence of noise disturbances on the servo system tracking precision was analyzed,and a noise disturbances observation and compensation control method was presented. Simulation results show that the proposed method can be used to effectively improve the tracking accuracy of servo feed system,and enhance the anti-disturbance ability.更多还原
