| 英文摘要 |
| Based on autoregressive moving average(ARMA) innovation model,white noise estimator and observation predictor,reduced-order Wiener state estimators for descriptor discrete-time stochastic linear systems were proposed by applying modern time series analysis approach.They can handle the filtering,smoothing and prediction problem in a unified framework and can reduce the computational burden.A simulation example shows their effectiveness. |
