Abstract

In this study, 2 degree of freedom PID controller is added to the conventional feed-forward controller for the purpose of improving its limitations such as set-point of tracking performance and disturbance suppression performance in the conventional PID controller. And the controller parameters optimization as a Real Coded Genetic Algorithm (RCGA) is used. Simulation and experiments verify the performance of the controller.

본 연구에서는, 자동으로 조작되는 밸브의 제어기로 사용되는 유압모션 제어기의 한계점인 설정치 추종성능과 외란 억제성능을 개선하기 위한 방법으로 기존의 PID 제어기에 피드-포워드 제어기를 추가한 2자유도(DOF) PID 제어기를 이용하였다. 이 제어기의 제어인자(Parameter)를 최적화시키는 도구로 실수코딩 유전알고리즘(Real Coded Genetic Algorithm, RCGA)을 이용하고 시뮬레이션을 통해 제어기의 성능을 검증하였다.
