摘要: 针对航空发动机工作安全边界,提出了一种基于切换控制的航空发动机控制系统设计方法.给出了切换控制策略的设计思路及切换稳定性的条件.给出基于混合灵敏度的航空发动机多回路切换鲁棒控制器设计方法,并构造了线性矩阵不等式.通过基于计算得到的控制器参数仿真表明,采用该切换方式相比于Min/Max切换方式消除了积分饱和在切换中延迟影响,提高发动机的动态响应能力及鲁棒性,同时可以保证切换的稳定性.Abstract: 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.
