| Abstract: | For a more accurate and more stable hydraulic servo system of the full-hydraulicleveler, from engineering reality that the spool control voltage was as an input signal and the cylinder displacement was as an output signal, a mathematical model was established herein based on high frequency response asymmetrical proportional servo valve controlling asymmetrical cylinder. The model was proved by simulation analysis and applications in the laboratory. |

| Keywords: | high frequency response asymmetrical proportional servo valve asymmetrical cylinder load pressure load flow complex leakage coefficient |
