servo element

Also the calculation and selection of hydraulic cylinder, servo valve and other major element parameter are completed.

其次，根据液压控制系统的设计要求设计了液压伺服系统的控制回路；完成了液压缸、伺服阀等主要元件的参数计算与选型；对液压伺服系统的数学模型进行了研究。

Hydraulic AGC system is been made of main dynamic element, which include signal conditioner 、 servo amplifier 、 hydraulic servo valve 、 fluid cylinder 、 mill roll and primary detector, etc. These elements have high nonlinear feature, the system have inevitably high nonlinear.

液压AGC系统主要由信号调节器、伺服放大器、电液伺服阀、液压缸、轧机辊系和传感器等组成，其中的液压器件具有高度非线性特点，其系统必然也具有高度的非线性。
