用山下法辨识旋压系统的频域模型

The Identification of Frenquency Domain Model of Spinning System by Using Y-method

讨论了用山下法辨识旋压系统的频域模型．并以我国第一套容器封头无胎冷旋压机为例．设计了系统的动态测辨电路．讨论了回归评价函数和矩阵参数的选择方法．该方法具有很好的收剑性．使用该方法得到的辨识模型．在工程应用中收到良好的效果．

The identification of frenquency domain model of a spinning system by using Y-method is discussed. As an example. the dynamic testing and identifying circuits of the spinning machine without spinning chock which is the first one in China have been designed.the parameters of its matrix have been selected and its evaluation function have been established. It is shown that the method has the feature of good convergence. The identifying model is excellent in the engineering application.
