摘　　要：针对目前电反馈伺服阀控制参数整定周期长、调试效果不理想的问题,介绍一种电反馈伺服阀控制参数的半物理整定方法。采用计算机数值模型代替真实模拟电路对伺服阀机械液压部分进行实时反馈控制;通过更改虚拟参数,得到半物理最优控制参数,并以此为依据调节实际模拟电路。试验表明,该方法相比直接调节模拟电路参数的方法具有参数调节范围大、调试及观测方便、调试数据实时保存等优点,适用于伺服阀研制开发阶段的结构参数优化试验,可以快速找到与当前结构参数匹配的控制参数,为新型电液伺服元件的研制提供技术支撑。Aiming at the problem that the control parameters tuning cycle of the electric feedback servo valve is long and the tuning result is not satisfactory,the semi-physical tuning method is introduced.Real-time feedback control of the mechanical and hydraulic part of the servo valve is realized by using the numerical model in the computer instead of the real analog circuit.The tuning of the control parameters are carried out by changing the virtual control parameters.The tuning process shows that this method has the advantages of large adjustment range of control parameters,convenient adjustment and observation,and real-time preservation of tuning data compared with traditional tuningmethod.Especially in the research and design stage of servo valve,matching control parameters can be quickly find for different combinations of structural parameters by this method which can provide technical supports to new electro-hydraulic servo components.
