  • A systematic framework of switching controllers design for aero engines according to the safe boundaries was presented.Firstly,an approach to design the switching strategy and stability conditions were proposed.Secondly,based on mixed sensitivity robust control and switching control theory,by constructing linear matrix inequalities,a sufficient condition was proposed in terms of matrix inequalities.The simulation based on calculated controllers' parameters shows that using the using switching strategy can eliminate the delay effect caused by integrator wind-up,and can improve the dynamic performance of the engine control system,and guarantee the stability in some peculiar occasions.
