Output-only road roughness identification from vehicle axle accelerations through a universal smoothing method
Zihao Liu, Daniel Dias-da-Costa, Tommy Chan +3
This paper presents an output-only method to identify road roughness profiles from axle accelerations of a moving vehicle. A two degree of freedom half-car model is discretised wit…

Experimental validation of universal filtering and smoothing for linear system identification using adaptive tuning
Zihao Liu, Sima Abolghasemi, Mohsen Ebrahimzadeh Hassanabadi +2
In Kalman filtering, unknown inputs are often estimated by augmenting the state vector, which introduces reliance on fictitious input models. In contrast, minimum-variance unbiased…
