摘要

Based on linear matrix inequalities (LMI) and quantitative feedback theory (QFT), a new design method of aeroengine robust controller was developed for uncertain mathematical model of aeroengine. The method has combined the design problem of frequency domain diagonal dominance pre-compensator and the solving process of LMI, thus achieving the decoupling of uncertain control objects. Moreover, a robust controller was designed with induction of QFT. The simulation results show that this method has good control efficiency and engineering applicability.
