Design of robust controller for the longitudinal autopilot system of BTT missile using QFT

QFT를 이용한 BTT 미사일 종방향 오토파일럿 시스템의 강인제어기 설계

A design method of robust controller for the longitudinal autopilot of BTT missile is considered. The difficulties are a set of linearized dynamic models which corresponds to different operating points has a wide range of parameters and it has even Non-Minimum Phase(NMP) zeros. In this paper, such a family of models is expressed by an interval plant. Then a robust control design method using QFT is represented. A simulation result shows that the proposed controller satisfies the given specification well.
