Abstract:For the complex networked control systems (NCSs) with finite-step correlated noises, multiplicative noises, multi-step random measurement delays and losses, we analyze the correlations between the noise and state, the noise and measurement, the noise and innovation, the measurement and innovation, and the state and innovation in terms of the step number of correlated noises. Moreover, the recursive formulas of correlation matrices are derived. The linear minimum variance optimal linear estimators, including filter, predictor and smoother, are presented by using projection theory. A simulation example of the three-tank water system under a network monitoring environment shows the effectiveness of the proposed algorithms.
