摘　　要：以FluidSIM软件为建模和仿真平台,构建液压系统电液比例压力控制的模型,分析模型结构、工作原理,并对系统压力控制的阶跃响应、正弦响应进行动态仿真。结果表明,相比于开环压力控制,采用参数优化的PID闭环压力控制,系统的调节时间缩短,响应加快,稳态误差减少,具有较好的动态特性和稳定性。With electro-hydraulic proportional pressure control system as the research object, which structure and working principle were analyzed and modeled and simulated with FluidSIM software as platform. Step response and sinusoidal response for system pressure control were simulated. The results show that compared with open loop pressure control, the parameter optimization of PID closed loop pressure control, reduce the adjustment time of system, speed up the response and reduce the steady- state error, has a good dynamic characteristics and stability.
