MRAC for Direct Drive Electronic-Hydraulic Servo System

Abstract:

In order to improve the accuracy, stability and rapidity of response, the paper built the mathematic model, and designed the high order system following the low order model based on Popov Hyperstable theory. Then applied this control method and PID method in actual system, compared them in time domain response. The result approves that the system owns better rapid and stable characteristics, satisfying the requirement when the direct drive electronic-hydraulic position control system changes its conditions. Further, improves that the theory is correct, certificates that the MRAC is very adaptive to the direct drive electronic-hydraulic servo system.
