对于一类具有状态和有限自动机输出时滞的离散混合系统,研究基于混合时滞观测器的混合反馈控制问题.通过系统线性部分和离散事件部分的Lyapunov函数构造了整个时滞系统的混合Lyapunov函数,进一步,给出混合反馈控制的设计方法且证明了闭环系统的稳定性.仿真例子说明该方法的有效性. For a class of discrete mixed systems with state and finite output automaton output delay, a hybrid feedback control problem based on hybrid time delay observer is studied. The hybrid Lyapunov system is constructed by the Lyapunov function of the linear and discrete events of the system. Function, further, the design method of hybrid feedback control is given and the stability of the closed-loop system is proved. The simulation example shows the effectiveness of the proposed method.
