Kalman filtering for continuous-time uncertain systems with Markovian jumping parameters

This paper studies the problem of Kalman filtering for a class of uncertain linear continuous-time systems with Markovian jumping parameters. The syst em under consideration is subjected to time-varying norm-bounded parameter uncertainties in the state and measurement equations. Stochastic quadratic stability of the above system is analyzed. A state estimator is designed su ch that the covariance of the estimation error is guaranteed to be within a certain bound for all admissible uncertainties, which is in terms of solut ions of two sets of coupled algebraic Riccati equations.
