提出了一种基于安全边界的航空发动机切换控制器设计的系统框架，首先给出了切换策略的设计方法和稳定性条件，然后基于混合灵敏度鲁棒控制和切换控制理论，通过构造线性矩阵不等式，利用矩阵不等式给出了一个充分条件，通过计算控制器参数的仿真结果表明，采用切换策略可以消除积分器饱和引起的时滞效应，改善发动机控制系统的动态性能，保证系统在某些特殊场合的稳定性。
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.
