摘要：For the discrete stochastic control systems with correlated noises, using the Kalman fil-tering method, based on the CARMA innovation model, a unified optimal fixed-interval whitenoise recursive Wiener smoother is derived. It contains high degree polynomial matrices with coef-ficient matrices exponentially decaying to zero. Further, by the truncation method, the corre-sponding fast suboptimal fixed-interval white noise Wiener smoothing algorithm is presented,which obviously reduces the computational burden. The error formula of the smoother and theformula of selecting the truncated index are given. A simulation example for Bernoulli-Gaussianwhite noise shows the effectiveness of the proposed results.
