Filtering for the out-of-sequence Measurement System with Limit Energy Noises

针对噪声能量有限网络系统的无序量测更新问题,利用延迟量测的预测估计和新息补偿的思想,提出了一种基于测量值求和形式H∞滤波器的无序量测更新方法。该方法能够利用系统参数的时不变性质,离线计算滤波参数,在无序量测发生与到达时,即能有效地处理,且能够保证滤波过程的实时性。该方法具有较强的扩展性,适用于参数不确定线性时不变系统的无序量测更新过程。仿真结果验证了所提方法的可行性。

In this paper,a filtering method of the out-of-sequence measurement networked systems with limited energy noises is proposed on the basis of predict-estimator and compensator.For the linear time-invariant systems,the filtering parameters could be computed outline.When the out-of-sequence measurement arrives at the filter center,the estimate can be updated easily and in real time.Moreover,this method can be easily extended to deal with the out-of-sequence measurement of the linear time-invariant systems with uncertain parameters.The final simulation illustrates the validity of the proposed method.
