The mathematical model of electro-hydraulic proportional control system of the HVD has been established in this paper. On the basis of this, the PID speed regulator has been lead into the control system in order to improve the response performance of the system. With the help of the simulation tool -Matlab, the mathematical models have been simulated. The simulation results prove that the mathematical model is reasonable. The control system with PID regulator has no overshoot and a more stable response performance after comparing and analyzing the characteristics of the common control system and that with the PID regulator. A more full and accurate theoretical foundation has been provided for finding applications of the HVD speed regulating technology.
