Input Forces Estimation for Nonlinear Systems by Applying a Square-Root Cubature Kalman Filter. [PDF]
Materials (Basel), 2017 This work presents a novel inverse algorithm to estimate time-varying input forces in nonlinear beam systems. With the system parameters determined, the input forces can be estimated in real-time from dynamic responses, which can be used for structural health monitoring.

Improved square root adaptive cubature Kalman filter [PDF]
IET Signal Processing, 2019 In this study, an improved square root adaptive cubature Kalman filter (ISRACKF) is proposed to improve the filter performance in terms of accuracy, computation efficiency, and robustness. Through the evaluated measure of non‐linearity value, the cubature rule under different accuracy levels can be adaptively selected in the dynamic process or ...
