Abstract

In this Study, another way to accomplish the goal of meeting large steam-flow requirements is the use of multiple valves. Multiple valves can provide better control in meeting the precision pressure controller requirements. Simulation demonstrates the effectiveness of the pressure controller. The key point of this study is to precisely control the position of the control valve on the outside of the electro-hydraulic system using a special PID controller. Simulation and experiments verify the performance of the controller.

본 연구에서는, 대형 증기유량이 요구되는 플랜트에서 정밀한 압력제어의 요구를 충족시키기 위한 다른 방법으로 3단계의 다중 제어밸브 구조를 이용하여 압력을 제어하는 제어기를 설계하는 내용이다. 본 연구의 핵심은 전기 유압시스템 외부에 별도의 PID 제어기를 이용하여 제어밸브의 위치를 정확하게 제어하는 것이다. 시뮬레이션 및 실험을 통해 제어기의 성능을 검증한다.
