چکیده
The use of the extended Kalman filter (EKF) is heavily eneenched in non-linear signal procesging applications. However linearisatioa erron inhenmt in the s p e c i f i i n of an EKF can severely degrade its performance. This paper presents a new approach to the robus-tification of the EKF by application of the robust linear design methods b d o n t h e € L wr"inimisationcritexion.

متن کاملA New Adaptive Extended Kalman Filter for a Class of Nonlinear Systems
This paper proposes a new adaptive extended Kalman filter (AEKF) for a class of nonlinear systems perturbed by noise which is not necessarily additive. The proposed filter is adaptive against the uncertainty in the process and measurement noise covariances. This is accomplished by deriving two recursive updating rules for the noise covariances, these rules are easy to implement and reduce the n...

State estimation is the foundation of any control and decision making in power networks. The first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. This paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...
