Fold-Hopf bifurcation, steady state, self-oscillating and chaotic behavior in an electromechanical transducer with nonlinear control

Autor: Manuel Pérez-Molina, Manuel F. Pérez-Polo

Publikováno v: Communications in Nonlinear Science and Numerical Simulation. 17:5172-5188

We investigate the nonlinear dynamics of an electromechanical transducer formed by a ferromagnetic mobile piece subjected to harmonic base oscillations. The normal form theory is applied to analyze the stability conditions of a Fold-Hopf bifurcation

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

Self-oscillating chaotic behavior and induced oscillations of a continuous stirred tank reactor with nonlinear control

Autor: Manuel Pérez-Molina, Manuel F. Pérez-Polo

Publikováno v: Chemical Engineering Journal. 191:512-527

We analyze the dynamical properties of a continuous stirred tank reactor (CSTR) to produce propylene glycol from propylene oxide with an excess of water containing sulfur acid and methanol assuming an exothermic pseudo-first order reaction. The self-
