摘要
研究受能量有界扰动影响的线性离散时变系统H∞故障估计问题.通过状态扩展,把故障估计问题转化为H∞滤波,并基于Krein空间的Kalman滤波理论,运用新息重组,给出了一种新的故障估计方法.算例验证了本文给出方法的有效性.
The H∞ fault estimation problem for linear discrete time-varying systems with energy-bounded disturbance is studied. Using state augment, the fault estimation problem can be formulated as an H∞ filtering problem. Then the fault estimator can be designed by using an innovative reorganizing approach in the framework of Kalman filtering in Krein space. Finally, a numerical example is given to show the effectiveness of the proposed method.
