An insight into instrumental variable frequency-domain subspace identification
(Pergamon-Elsevier Science LTD, 2010)
In this paper, we study instrumental variable subspace identification of multi-input/multi-output linear-time-invariant, discrete-time systems from non-uniformly spaced frequency response measurements. A particular algorithm, ...
Frequency domain subspace-based identification of discrete-time singular power spectra
(Elsevier Science BV, 2012)
In this paper, we propose a subspace algorithm for the identification of linear-time-invariant discrete-time systems with more outputs than inputs from measured power spectrum data. The proposed identification algorithm ...
An H-infinity and Skyhook Controller Design for a High Speed Railway Vehicle
(Elsevier Science BV, 2018)
The electronic-based recently developed railway vehicles compromising at high speeds by consuming eco-friendly energy and providing better transportation facilities without complicating the car designs. In this study, the ...
Track Modelling and Control of a Railway Vehicle
(Elsevier Science BV, 2016)
In this paper, a railway vehicle AM96 train developed by Bombardier, Belgium is represented as a half-car model. First, random road defect inputs are modelled as track class 6 from Federal Railroad Administration (FRA) ...
Effect of Multi-Objective Control on Ride Quality in High Speed Railway Vehicle
(Elsevier Science BV, 2016)
The railway transportation has a significant impact on both the freight and passenger carriage, therefore it should provide a comfortable, safe, fast and inexpensive riding. In this paper, a six-degree-of-freedom half-car ...
Influence of Wheel-Rail Contact Stiffness on the H-2 Controlled Active Suspension Design
(Elsevier Science BV, 2017)
In this work, the mathemtical model of a railway passenger car with conventional and radial-elastic wheels is analyzed. Stochastic excitations are applied to the wheelsets. The local elasticity between the wheel and the ...
Road Profile Modeling by Subspace Identification Methods
(IEEE, 2015)
In this paper, spectral models of road profiles using nonparametric and subspace identification methods are developed from road elevation measurements. First, power spectra of road profiles are estimated on uniform grids ...
Rail Track Modelling by Using Identification and Curve Fitting Techniques
(IEEE, 2018)
In this paper, a seventeen-degree-of-freedom full-car model of a high speed railway vehicle excited by real track profile is going to be studied. The field measurements are collected by Turkish State Railways (TCDD) on a ...
Spectral Modeling of Longitudinal Road Profiles
(IEEE, 2015)
In this paper, for a quarter-car model, we derive covariance expressions for the MIRA spectrum and calculate the root-mean square outputs for the ISO 8608 classified roads. The derived results are compared with existing ...
Stochastic Models for Parallel Road Tracks
(IEEE, 2016)
In this paper, we propose a method for constructing road roughness on parallel tracks. This method uses empirical power spectral densities and coherence of the left and the right-tracks estimated by non-parametric methods. ...
