Stability investigations based on two-port describing functions

Janos Ladvanszky

Stability of a nonlinear, tuned amplifier has been investigated based on the describing function method. On stability, this paper means global asymptotic stability. The tuned…

Design of the variable frequency oscillator in DC-DC converter

Tian Lei, Nan Gong, Li Wang, Qin Qin Li, Heng Wei Wang

Because of the logic delay in the converter, the minimum turn on time of the switch is influenced by the constant time. When the inductor current gets to the threshold of the…

The resin-flowing model in prepreg lamination of print circuit board

Shitao Liu, Rong Cui, Hongwei Cao, Jinhong Qiu

This paper aims to show a resin-flowing model based on Darcy’s law to display the flowing properties of prepreg during lamination. The conformity between the model and…

Stabilization and circuit implementation of a novel chemical oscillating chaotic system

Li Xiong, Wanjun Yin, Xinguo Zhang

This paper is aimed at investigating a novel chemical oscillating chaotic system with different attractors at fixed parameters. The typical dynamical behavior of the new chemical…
