Nonlinear ball and beam control system identification
(2014)
The Ball and Beam system is a common didactical experiment in control laboratories that can be used to illustrate many different closed-loop control techniques. The plant itself is subjected to many nonlinear effects, which ...
Video analysis-based estimation of bearing friction factors
(2018-10-18)
Friction is an inherent factor in any real physical system, affecting, as it is
natural, the dynamics of the entire system. In particular, the computation of
friction losses are of special interest because friction factors ...
Determinação das deformações limites de chap as metálicas anisotrópicas considerando o atrito no estiramento com punção
(2010-12-01)
This work aims at determining the influence of anisotropy of the material using the new Hill's quadratic and friction on the prediction of strain limits for using analysis of formability of sheet metal forming limit diagrams. ...
Video-based analysis of the transition from slipping to rolling
(Cornell University, 2019)
The problem of a disc or cylinder initially rolling with slipping on a surface and subsequently transitioning to
rolling without slipping is often cited in textbooks [1-2]. Students struggle to qualitatively understand ...
Using feed-forward perceptron Artificial Neural Network (ANN) model to determine the rolling force, power and slip of the tandem cold rolling
(ISA - Instrumentation, Systems, and Automation SocietyUnited States, 2023)
MODELING AND ANALYSIS OF A BALL AND BEAM SYSTEM INCLUDING IMPACTS AND DRY FRICTION
(Amer Soc Mechanical Engineers, 2014-01-01)
The Ball and Beam system is a common didactical plant that presents a complex nonlinear dynamics. This comes from the fact that the ball rolls over the beam, which rotates around its barycenter. In order to deduce the ...
Adaptation for tandem cold mill models
(ELSEVIER SCIENCE SA, 2009)
The ideal conditions for the operation of tandem cold mills are connected to a set of references generated by models and used by dynamic regulators. Aiming at the optimization of the friction and yield stress coefficients ...
