摘　　要：介绍同轴式电液比例流量阀的结构特点、静动态模型及实验研究,理论分析与实验结果一致,为阀的优化设计提供了理论基础。采用流量反馈及前向通道的PID调节,有效地提高了阀的静动态特性。The structure features, static and dynamic characteristics, theoretical analyses and experimental results of the coaxial flow control valve were described. It provides theoretical basis for optimal design because the experimental results are agreed with the theoretical analyses. The static and dynamic characteristics can be improved by flow feedback and PID regulation in forward path.
