By means of Matlab/Simulink toolbox,dynamic structure of the position control system was put forward and the mathmetical model of position control system in hydraulic AJC was aslo constructed with which we could practice the dynamic simulation.

• 利用M atlab/S imu link得到了位置控制系统的动态结构框图,建立了用于液压踏步位置控制系统动态特性分析的数学模型,实现了动态仿真。
