An equation of state based on the intermolecular potential and the radial distribution function to estimate the virial coefficients by using PvT chaotic data
Autor: Manuel Pérez-Molina, Javier Gil Chica, Elena Fernández Varó, Manuel F. Pérez-Polo
We derive a new equation of state (EOS) for any non-polar, polar or quantum gas and any intermolecular potential through an approximation of the radial distribution function based on the Ornstein-Zernike equation. Such EOS is applied to estimate the

This paper analyzes how to determine the virial coefficients B and C of real gases by using a theoretical device whose pressures and densities oscillate in chaotic regime. The device is formed by a valve, a pressure controller, a pressure probe and a

This paper analyzes the behavior of nitrogen inside a closed cylinder with a mobile piston actuated by a nonlinear spring, a viscous damper and a control force which compensates partially the effect of the high gas pressure. Two helical heating coils

Stabilization and positioning control of a rolling disk by using the Bogdanov–Takens bifurcation
Autor: Javier Gil Chica, Manuel F. Pérez Polo, Manuel Pérez Molina
Publikováno v: Physica D: Nonlinear Phenomena. 241:1450-1469
On the basis of Bogdanov–Takens bifurcation, we obtain two nonlinear control laws for stabilization and positioning of a rolling disk on a horizontal plane at a desired set point. The first control law is applied to reach a set of predetermined poi

Swing-up and positioning control of an inverted wheeled cart pendulum system with chaotic balancing motions
Autor: Javier Gil Chica, Manuel Pérez Molina, Manuel F. Pérez Polo
Publikováno v: International Journal of Non-Linear Mechanics. 47:655-665
This paper explores the problem of swinging-up an inverted pendulum formed by a rod attached to a wheeled cart with a hanging bob at its opposite end. The system is driven by the wheeled cart platform system, which is formed by a cart, wheels with co

Stability and chaotic behavior of a PID controlled inverted pendulum subjected to harmonic base excitations by using the normal form theory

Publikováno v: RUA. Repositorio Institucional de la Universidad de Alicante
Universidad de Alicante (UA)
In this paper we investigate the stability and the onset of chaotic oscillations around the pointing-up position for a simple inverted pendulum that is driven by a control torque and is harmonically excited in the vertical and horizontal directions.

Publikováno v: RUA. Repositorio Institucional de la Universidad de Alicante
Universidad de Alicante (UA)
This paper studies the stabilization, tracking of a predefined trajectory and how to reach a desired set point for a wheel which is rolling on a horizontal plane without slipping. For this purpose, the wheel is controlled by small torque generated by
