Using a limited number of sampled-data of system output, a stochastic finite-memory model may be established to take the place of the system state equation used in the Kalman filter to perform one-step optimal prediction. On this basis, two sets of equations of the "minimum mean-square-error" discrete filter are derived. When the system state equation is unknown, the system state can be estimated with the method developed in this paper.

In the past,digital filters were single-rate systems without exception.The use of multi-rate digital filters has been proposed in recent years.The multi-rate digital filter is a digital system in which the output sampling rate differs from the input sampling and/or interval processing rate.This paper systematically introduces the basic theory,analysis,implementation techniques and applications of these filters.In this paper,the relation between modified Z transforms and ordinary Z transforms,the agreement of calculating the values of sampling intervals by means of the modified Z transforms and the sampling inversions,the agreement of general analysis by means of sampling inversions and the analysis of periodically time-varying discrete filters with multi-rate filters as a special case,have been derived and stated.

Time series analysis techniques have been successfully used in the parameter identification of structures. In this paper, a digital filtering technique is developed to reduce the adequate order of the Autoregressive Moving Average Vector(ARMAV) model so as to overcome the difficulties associated with the higher order modeling. Problems in digital filtering with the ARMAV model are analyzed, including the selection of an appropriate filter, the methods of transformation from an analog filter to discrete filter, and the time reversal method for eliminating the phase distortion. Finally, a simulation example and experimental results are illustrated using the digital filtering technique presented herein.
