航空发动机分布式控制系统指数稳定性分析
Stability analyzation of aero-engine distributed control system

摘要: 建立具有时延与数据包丢失的航空发动机分布式控制系统模型,模型为一类异步动态系统,基于Lyapunov第二法和线性矩阵不等式方法推导了系统的指数稳定性判定定理,根据该判据可以得到分布式控制系统的指数稳定意义下的状态反馈控制律,数字仿真说明了该判据的有效性.Abstract: The aero-engine distributed control system(DCS) with time-delay and data-packet dropout was established as an asynchronous dynamical system.Exponent stability of the system was presented using 2nd Lyapunov method and linear matrix inequalities(LMI) formulation,and the state-feedback control parameters of DCS could be obtained according to the stability criterion.Simulation examples show that the stability criterion is feasible.
