영점구조를 이용한 비 최소위상 플랜트의 새로운 LQG/LTR 방법연구
A study on a new method of LQG/LTR for nonminimum phase plant by using zero structure
초록
LQG/LTR method cannot applied to nonminimum phase plant. In this paper, we present a new approximation method which guaratee the approximation error equal to zero and exact loop transfer recovery. Zero structure of plant and approximated plant are considered in approximation procedure. It is shown that the properties of plant and approximated plant at pole and zero frequency response are exactly same. It is shown by example that the suggested method can avoide the NMP plant constraint arised in designing LQG/LTR.
