Abstract

This paper presents a design method for the robust flight controller of a hyghly maneuvering aircraft subject to C.G variation. This method is based on LMI(Linear Matrix ZInequality) pole-placement design methodology for the polytopic models. Simulation results show that the proposed LMI-based pole-placement design methodology robustly yields uniform performance with adequate Flying Qualities (FQ) over the entire CG variation range.
