초록

본 논문은 제어성능 향상을 위하여 하이브리드 퍼지 제어기 설계를 제안 하였다. 하이브리드 퍼지 제어기 설계 방법은 PID 제어기와 퍼지제어기를 병렬로 결합한 방법으로, 본 논문에서는 PID 제어기는 IMC 구조를 갖는 PID 제어기로 성능지수 (IAE, ITAE IATAE)값이 최소가 되도록 자동 동조 하였고, 퍼지 제어기의 환산계수(GE, GD, GH, GC)값은 유전자 알고리즘을 이용하여 구하였다. 시뮬레이션을 통하여 다양한 공정에 대하여 본 논문에서 새롭게 제안된 방법이 기존의 방법보다 우수함을 확인 할 수 있었다.

In this paper, we propose a hybrid fuzzy controller for high performance. Hybrid fuzzy controller are combined Fuzzy and PID controller. In tuning the controller, the parameters of PID and the factors fuzzy controllers were obtained from the model identification and by using genetic algorithms, respectively. Simulation examples demonstrated a better performance of the proposed controller than conventional ones.
