In this paper several dynamic testing methods of electrohydraulic servo systems are introduced, including stochastic noise test, hammering test and sweep frequency test.
本文介绍电液伺服系统的几种动态测试方法，包括随机噪声测试，锤击法测试和扫频测试。

The dynamic hybrid, using a new type of mixer, servo motor control, speed adjustable, and the noise is very small.
选用动态混合时，采用新型混合器，伺服电机控制，转速可调，而且噪音很小。

But how to ensure the rapid response speed and the good noise-proof-feature is the issue we faced, this required some essential analysis of the servo capability.
