Basic bifurcation analysis of a hysteresis oscillator

This paper carries out a basic bifurcation analysis of a 'smooth' version o f a recently proposed piecewise-linear oscillator based on hysteresis. The analysis is made referring mainly to two circuit parameters particularly ea sy to vary in a laboratory implementation of the circuit. By resorting to b oth analytical and numerical analyses, some local and global bifurcations o f the dynamics of the oscillator are pointed out. The reported results comp letely agree with PSPICE simulations and experimental measures. Copyright ( C) 2001 John Wiley & Sons, Ltd.
