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。

But the set up time reduction slowed observably, as the power supply voltage was increased to about 3 times as large as the servo amplifier output voltage corresponding to rated current.

随着电源电压的增大，控制电流建立时间减小，当电源电压达到伺服放大器额定控制电流所对应的输出电压的3～4倍以上时，电源电压对提高伺服放大器动态性能的作用明显减弱。

In high precision DC servo system, the PWM power amplifier based on power electronic devices is mainly used.

在高精度伺服控制系统中，大多采用基于电力电子器件的脉宽调制型功率放大器，简称PWM功率放大器。

Simulation results show that servo amplifier gain is the main factor affecting system performance in the control system.

仿真结果表明，在角度控制系统中，伺服放大器增益是影响系统性能的最主要因素。

The experiment results show that phase phenomena are probably caused while the servo amplifier gain and the amplitude of input signal increase to some extent.

实验结果表明，当伺服放大器增益和输入信号的幅值较大时都有可能促成系统的相位突变。
