摘　　要：针对l2-l∞性能这一类扰动抑制度指标设计滤波器,使滤波误差系统是鲁棒D(a,r)-稳定的(当外部扰动恒为零时),且l2-l∞性能指标上界尽可能的小.采用线性矩阵不等式方法,给出了l2-l∞滤波器存在的充分条件,进而提出滤波器的设计方法.通过数值算例验证了该方法的可行性.The objective is to design a filter which guarantees that the filter error system is robust D（a,r） -stable, i. e. , all poles are located inside the pre-specified disk on the complex plane, while the upper bound of the l2-l∞ performance index is as small as possible. Base on linear matrix inequality approach, a sufficient condition for the existence of the filter is presented, and then a design method of such filter is proposed. A numerical example is provided to demonstrate the effectiveness of the proposed method.
