Abstract :
This paper addresses the design of robust one step predictor filter for linear discrete-time systems subject to time-varying and norm bounded uncertainties in every system matrices. The dynamic and measurement noises are allowed to be correlated with unknown time-variant cross-covariance. The proposed filter guarantees a minimal upper bound error variance on the state estimation. A numerical example is given to illustrate the results.
