The design problems of mixed l_1/ H_ ∞ filter for linear discrete-time uncertain systems are dealt with. The aim is to design a linear asymptotically stable filter which guarantees that the filtering error system has the different performance in the different filtering channel. 研究离散时间不确定线性系统的混合l1/H∞滤波器设计问题,目的是找到一个稳定的线性滤波器,使滤波误差系统在不同的滤波通道内具有不同的性能指标。
