Such filters propagate mean and covariance based on sigma points, like Unscented Kalman Filtef (UKF) [56] or Sigma Point Kalman Filter (SPKF) [57].
The sigma-point Kalman filters (SPKF), a family of filters based on derivativeness statistical linearization achieves higher performance than EKF for many problems and is applicable to areas where EKFs cannot be used, such as unscented Kalman filter (UKF) and center difference Kalman filter (CDKF) [16-18].
In recent years, a new class of filter known as sigma-point Kalman filter (SPKF) has attracted a great deal of attention.
