Chaos in electronic circuits and studies of bifurcation mechanisms

We study the chaotic memristic circuit proposed by Chua and Muthuswamy and analyze the behavior of the voltage of the memristor, capacitor and that of electric currents. We add harmonic voltage to the memristor, and study nature of Strange Nonchaotic Attractor (SNA) and soft chaos. We compare the chaotic circuit proposed by Chua, Komuro and Matsumoto in 1986, and that we analyzed in 2008, and whose SNA was observed by Zhu and Liu in 1997.
