Abstract: Aiming at solving the problem of random noise and process noise in the follow up and elimination control system of vibration dependent output system the sliding mode controller based on Kalman filter was researched. The sliding surface was designed to ensure the static tracking of the output of the vibration force. The exponential approximation law was used to improve the approach speed and weaken the buffeting. For the case of noise interference， the Kalman filter was added to the control system to eliminate the random noise and process noise caused by the sensor measurement. On the Matlab / Simulink platform， the vibration sine output force following simulation was researched. The results indicate that the sliding mode vibration follower system based on Kalman control has Strong anti noise， robustness and good steady state performance compared with Kalman filter and no Kalman filter tracking effect.
