| Abstract: | This paper introduces the structure and principle of P-Q servo-valve, presents its bond graph model after dealing with the flow functions and force(torque) functions of components. There are many advantages when P-Q servo-valve is used in electro-hydraulic force control systems. The bond graph model of electro-hydraulic force control system is established. The simulation results accord with experiment ones, which consequently proves that the bond graph models of electro-hydraulic force control system and P-Q servo-valve are valid. |
