  • 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.
