Design and Characteristic Analysis on Servo Amplifier

Abstract:

With the rapid development of the electro-hydraulic servo control technology, the application of electro-hydraulic servo valve has become more and more widely. Servo amplifier is an important part of the electro-hydraulic servo control system to drive and control servo valve. This essay introduces the principle and the function of servo-amplifier, and designs a servo amplifier with the functions of proportional amplifier, zero adjustment, feedback and current limitation. The performance analysis and validation for the servo amplifier are carried out by using simulation software EDA .On the basis of the simulation, the servo amplifier is fabricated, and its performance is tested. The results indicate that the servo amplifier has features of stable current output, good linearity, rapid response, and fully meet designing requirements.
