The Analysis of Dynamic Characteristics and the Control of Compressed Gas Expulsion System Using Electro-Hydraulic Servo Valve
전기.유압 서보밸브를 이용한 압축가스 방출시스템의 동특성 해석 및 제어
Abstract
A dynamical analysis and PID control of a compressed gas expulsion system is performed. The purpose of this study is to develop a compressed gas discharging system and to verify the validity of the system. The electro-hydraulic servo valve is modeled as a 3th order transfer function to calculate flow force affecting expulsion valve is significantly considered. The friction force in the expulsion valve is considered as a nonliner model of stribeck effect. The dynamic characteristics of this system is examined by the computer simulation. The position control of the expulsion valve is performed by PID controller.
