Title: Localization of hidden Chua attractors by the describing function method,
Abstract: In this paper the Chua circuit with five linear elements and saturation
non-linearity is studied. Numerical localization of self-excited attractor in
the Chua circuit model can be done by computation of trajectory with initial
data in a vicinity of an unstable equilibrium. For a hidden attractor its basin
of attraction does not overlap with a small vicinity of equilibria, so it is
difficult to find the corresponding initial data for localization. This survey
is devoted to the application of describing function method for localization of
hidden periodic and chaotic attractors in the Chua model. We use a rigorous
justification of the describing function method, based on the method of small
parameter, to get the initial data for the visualization of the hidden
attractors. A new configuration of hidden Chua attractors is presented.
