Abstract

We study the optimal networked estimation of a kind of Linear Time Invariant (LTI) or determinate parameters systems with uncertain "Out-Of-Sequence" Measurement (OOSM) induced by random communication delays.Both available properties

which are off-line computation of filter’s parameters for these systems and linear weighted combination for the Linear Minimum Mean Square Error (LMMSE) estimate

are fully used to present the weighted summation form of the Kalman filter (KF).Afterward

two optimal delayed filters for different uncertain OOSM systems are proposed on the basis of the linear weighted summation filter.At last

four simulation examples are demonstrated to validate the effectiveness and superiority of the proposed networked estimators.
