Abstract

This work plan addresses stability of Kalman filters for stochastic systems, with emphasis on discrete-time systems with Markov jump parameters. Obtaining conditions for stability of the Kalman filter is a relevant issue, as stability is a key feature for applications. Our group have been dealing with stability of filters and necessary and sufficient conditions have been obtained for linear time-varying systems; in the present work we seek for a stability notion and conditions that are typical of linear Markov jump systems, e.g. allowing to take the transition probability matrix into account.
