摘　　要：针对汽车发动机缸体清洗设备行程控制系统中的双缸同步问题,介绍了一种用伺服比例阀控制的主从式液压同步控制系统。为了减小双缸同步误差,提高系统的动态性能,此系统采用了比例积分微分(PID)控制算法。运用Matlab/Simulink工具建立PID控制算法和系统仿真模型,对系统进行了单位阶跃信号的仿真分析。Aimed at the double cylinder synchronization problems arising from the stroke control system of automobile engine cylinder cleaning equipment,a master- slave hydraulic synchronous control system controlled by servo proportional valve is introduced. In order to reduce the synchronization error of the double cylinders and improve the dynamic performance of the system,a PID control algorithm is adopted in this system. The PID control algorithm and the system simulation model are established by using Matlab / Simulink tool. Then the simulation analysis of unit step signal of the system is carried out.
