Parametric excitation and Hopf bifurcation analysis of a time delayed nonlinear feedback oscillator
Sandip Saha, Gautam Gangopadhyay, Sangeeta Kumari +1
In this paper, an attempt has been made to understand the parametric excitation of a periodic orbit of nonlinear oscillator which can be a limit cycle, center or a slowly decaying…
Systematic designing of bi-rhythmic and tri-rhythmic models in families of Van der Pol and Rayleigh oscillators
Sandip Saha, Gautam Gangopadhyay, Deb Shankar Ray
Van der Pol and Rayleigh oscillators are two traditional paradigms of nonlinear dynamics. They can be subsumed into a general form of Liénard--Levinson--Smith(LLS) system. Based on…
Suppressing birhythmicity by parametrically modulating nonlinearity in limit cycle oscillators
Sandip Saha, Sagar Chakraborty, Gautam Gangopadhyay
Multirhythmicity, a form of multistability, in an oscillator is an intriguing phenomenon found across many branches of science. From an application point of view, while the multirh…
