摘　　要：从DBETR型比例压力溢流阀结构出发,先建立比例阀控制压力系统的待辨识模型,再采用经典的阶跃响应法辨识系统参数,得到工程上适用的系统简化模型。仿真结果和实验结果的对比表明,所建立模型的有效性。A on-identify model of proportional valve pressure controlled system was established though analyzing the configuration of DBETR type proportional pressure relief valve firstly, and then using classical step response method to identify system parameter, a practicable system, simple model was deduced at last. The comparison between results of simulation and experiment validate the established model.
