Modelling an Inertia Wheel Pendulum Benchmark
(Taylor & Francis, 2005-09)
In this paper, modelling and parameter identification of an inertia wheel pendulum benchmark is considered. This is an underactuated mechanical system useful for teaching and research. Attention is focused on deriving a ...
A simplified model for friction compensation in precise feed drives
(Inderscience Enterprises, 2018-11)
Friction is a complex phenomenon with negative effects on the precision of positioning systems. In this work, a single-state friction model for control purposes, aimed to simplify the implementation of control algorithms ...
Two-State GMS-Based Friction Model for Precise Control Applications
(Springer, 2016-05)
The capability of a model to represent the complex friction behavior is particularly important for systems where friction has a major impact on motion precision. In this work a GMS-based model is proposed which would require ...
Simulations of turbulent channels with prescribed velocity profiles
(Cambridge University Press, 2013-05)
Direct numerical simulations of turbulent channels with artificially prescribed velocity profiles are discussed, using both natural and purposely incorrect profiles. It is found that turbulence develops correctly when ...
Differential equation for the flow rate of discharging silos based on energy balance
(American Physical Society, 2020-05)
Since the early work of Hagen [G. H. L. Hagen, Ber. Verhandl. K. Preuss. Akad. Wiss. Berlin 17, 35 (1852)] and Beverloo et al. [W. Beverloo et al., Chem. Eng. Sci. 15, 260 (1961)], the flow rate of granular material ...
