Abstract
This paper is concerned with optimal linear estimation problem for networked systems with random delays and packet dropouts.Two Bernoulli distributed random variables are employed to describe the phenomena of possible one-step random delay and multiple packet dropouts in data transmission by networks.Based on an innovative analysis approach,the optimal linear filter,predictor and smoother for the state are presented in a linear minimum variance sense.They are solved based on a Riccati equation and a Lyapunov equation.A sufficient condition for the existence of the steady-state estimators is given.A simulation example verifies their effectiveness.
