研究了离散时间线性脉冲奇异系统的有限时间滤波问题。利用线性矩阵不等式方法，首先给出了滤波误差系统有限时间稳定和满足性能要求的充分条件，然后给出了脉冲奇异系统有限时间滤波问题可解的充分条件，并且给出了滤波器的设计方法，推广了脉冲系统有限时间滤波理论结果。最后通过数值算例表明了结论的可行性。

The finite-time filtering problem for discrete-time linear impulsive singular systems was investigated.Firstly, sufficient conditions for the filter error system which is finite-time stable and satisfies the performance requirements were given by using the linear matrix inequality method.Secondly,sufficient conditions for solving the finite-time filter prob-lem of impulsive singular systems were presented,and the designing method of filter was provided,which generalizes the finite-time filtering theories of impulsive systems.Finally,a numerical example was given to demonstrate the feasi-bility of the conclusion.
