Summary: This paper presents a convergence analysis of the modified unscented Kalman filter (UKF) as an observer for a class of nonlinear deterministic continuous time systems, comparing it with the extended Kalman filter (EKF) and highlighting the differences in convergence behavior. The study shows that the UKF is not an exponentially converging observer like the EKF, and proposes the unscented Kalman observer as a better candidate for observation. This work serves as a first step towards proving the global convergence of the high-gain version of the UKF observer.

Summary: This paper presents an estimator that combines the Unscented Kalman Filter (UKF) technique with multibody system dynamics to determine the state of flexible multibody applications. By translating physical measurements into non-physical modal coordinates, this novel technique overcomes the challenge of not being able to directly obtain information about reference and modal coordinates from sensors. Simulation results on a four-bar mechanism demonstrate the effectiveness of the proposed modeling technique in accurately determining the state of nonlinear flexible multibody systems.
