中文摘要 |
研究了一类Delta算子描述的线性系统非脆弱H∞滤波问题. 所设计的滤波器具有乘性的滤波器增益变化.采用线性矩阵不等式方法, 给出H∞滤波器存在的充分条件, 所设计的滤波器在一定的乘性参数变化情况下, 仍能保证滤波误差系统渐近稳定, 且具有一定扰动抑制性能. 数值仿真例子说明了设计方法的有效性. |
英文摘要 |
The non-fragile H-infinity filtering for a class of linear systems described by Delta operator is investigated. The designed filter is assumed to be with multiplicative filter gain variations. The sufficient condition is developed for the existence of the non-fragile filter design in terms of linear matrix inequality(LMI), and the obtained non-fragile H-infinity filter guarantees the filter error system of asymptotic stability and prescribed disturbance attenuation performance for a restricted variation of filter gain. The numerical example illustrates the feasibility and advantage of the proposed designs. |
