中文摘要
      基于多项式ARMA新息模型方法提出了随机奇异线性离散时间系统的稳态最优估计.估值器的增益矩阵是通过新息分析和射影方法推得;其计算归结为求解一个多项式方程和谱分解.这一结果是最优估计多项式方法在奇异系统中的应用.
英文摘要
      The steady-state optimal estimation of singular systems is studied by applying ARMA innovation model.The key problem is the calculation of estimation gain matrix,which is obtained from the uniqueness of the ARMA innovation model.The estimator is computed in terms of the solution to one polynomial equation and spectral factorization.
