Fourth , use MATLAB/SIMULINK to carry on dynamic simulation to the hydraulic system selected for used and control device, studying the pump exports the pressure , flow and change of outputting the rotational speed of motor in case of changing in load.

• 四是使用 MATLAB/SIMULINK对所选用的液压系统及控制装置进行了动态仿真,研究在负载变化的情况下,泵出口压力、流量和马达输出转速的变化情况。
