R. Genesio et al., A FREQUENCY APPROACH FOR ANALYZING AND CONTROLLING CHAOS IN NONLINEARCIRCUITS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 40(11), 1993, pp. 819-828
The paper presents a frequency domain approach for studying the chaoti
c dynamics of an important class of nonlinear circuits. By formulating
an elementary model of chaos and using the harmonic balance principle
, techniques for the analysis and the stabilization to a periodic solu
tion of complex systems are developed. They result in engineering tool
s which are simple and practical, although not rigorous in principle,
providing a qualitative view of the global dynamics in study. Some app
lications concerning the recent unfolded Chua's circuit are considered
.
