Identification of time-varying nonlinear structural physical parameters by integrated WMA and UKF/UKF-UI

Nonlinear Dynamics, 2021
The identification of time-varying physical parameters of nonlinear systems is still a challenging task. Limited studies based on the wavelet multiresolution analysis (WMA) have been attempted, which requires full measurements of structural displacement, velocity and acceleration responses of all degrees of freedom and exact information of external ...

Geomagnetic orbit determination: EKF or UKF?

open access: yesAircraft Engineering and Aerospace Technology, 2021
Purpose Autonomous orbit determination using geomagnetic measurements is an important backup technique for safe spacecraft navigation with a mere magnetometer. The geomagnetic model is used for the state estimation of orbit elements, but this model is highly nonlinear.

Nonlinear Target Identification and Tracking Using UKF

open access: yes2007 IEEE International Conference on Granular Computing (GRC 2007), 2007
In this paper, we implemented target identification algorithm using Dempster Shafer theory (DST) and tracking algorithm using extended Kalman filter (EKF) and unscented Kalman filter (UKF). A tracking filter is developed and simulated based on UKF to track nonlinear, ballistic and reentry targets.

Research on Trajectory Tracking Algorithm Based on LSTM-UKF

2021 7th IEEE International Conference on Network Intelligence and Digital Content (IC-NIDC), 2021
Aiming at the problems of excessive error and inability to track the traditional target tracking algorithm in the absence of observations, a trajectory tracking model combined with Long Short-Term Memory (LSTM) is designed.
