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.
