In order to make the static pressure workbench maintain the best oil film thickness, a compensation control scheme of the oil film thickness was proposed based on adjusting the motor speed and controlling flow of multihead pump. The hydraulic control principle of the control scheme was introduced, and then a corresponding control flow chart and the mathematical model of each part were established, afterwards, the relevant control model system was put up by using SIMULINK module of the MATLAB. The simulation parameters are set up to simulate, which verifies the feasibility of the intelligent compensation method and the control system in the end.
