摘要
确定电液伺服阀的数学模型为三阶形式,根据电液伺服阀幅频,相频特性曲线(电液伺服产品样本提供),运用单纯形寻优法确定电液伺服阀的模型参数.此模型可避免较大误差.为控制系统设计提供较好的电液伺服阀的数学模型.
The model of electrohydraulic servovalve is considered as third order system.Parameters of medel of electrohydraulic servovalve are determined by means of simplex form optimization given according to the magnitude versus-frequency plot and phase-versus-frequency plot of electrohydraulic servovalve (offered by the manufacturer) the method can supply a more precise mathematical model of electrohydraulic servovalve for the design of control system
