Abstract

The electric furnace, inside which the desired temperature is kept by the generated heat, is known to be a difficult system to control and model exactly because system parameters and response delayed time are varied as the temperature and positions are changed. In this study, the GPCEW (generalized predictive control with exponential weight), which always guarantees the stability of the closed loop system and can be effectively applied to the internally unstable system, was introduced to the ceramic drying electric furnace and was verified by showing its temperature tracking performance experimentally.

내부에 열을 가하여 원하는 온도를 유지하는 전기로는, 정확하게 제어하고 모델링을 하기 힘든 시스템이다. 왜냐하면 시스템 변수와 응답 지연 시간이 온도와 위치가 변함에 따라 변하기 때문이다. 이번 연구에서 항상 폐루프 시스템에서 안정성을 보증하고, 내부가 불안정한 시스템에 효과적으로 적용될 수 있는 가중계수를 갖는 일반형 예측 제어가 세라믹 전기로에 적용되었고, 실험을 통해 온도 추적 이행을 보임으로서 확인하였다.
