轧钢机液压伺服系统的数模辨识

Identification of hydraulic pressure servo system

研究相关法在液压弯辊伺服系统数学模型辨识中的应用，分析和计算脉冲响应、频率特性和传递函数之间的转换关系，最后得到三阶的系统辨识模型。

The appliation of interrelative method in the identification of hydraulic servo system is researched, the transform relations between pulse response, frequency characteristic and tansfer functions are analyzed and calculated. In the end, a three order mathematic modle of hydraulic hydraulic pressure servo system.
