중복된 입력변수를 갖는 공정에서 이들 변수를 모두 조작변수로 사용하는 루프제어방법을 제시하였으며, 여분의 조작변수를 일정한 값에 고정시키는 기존의 방법과 비교할 때 제어성능과 안정성이 개선될 수 있음을 주파수 영역에서 해석하였다. 회분식 반응열 분석 시스템의 온도제어에 제시된 제어방법을 적용한 결과 제어성능이 향상됨을 확인할 수 있었다.

A loop control method, where all potential manipulated variables are actively utilized, is proposed for a process which has redundant manipulated inputs. Through analyses in the frequency domain, it was shown that the performance and stability of the proposed method are improved in comparison with those of the conventional method where extra manipulated variables are fixed at constant values. For experimental evaluation, the proposed method was applied to temperature control of a batch reaction calorimeter. As a result, tracking as well as regulation performances were found to be greatly improved compared to the conventional approach.
