Hopf bifurcation in a van der Pol type oscillator with magnetic hysteresis

We consider models of electronic oscillators of van der Pot type assuming magnetic hysteresis in inductance element. The Preisach nonlinearity is used to model the hysteresis relation. We study local and global behaviour of the branch of cycles originating from the Hopf bifurcation point. (c) 2007 Elsevier B.V. All rights reserved.
