Chaotic Duffing type oscillator with inertial damping

Abstract

A novel Duffing-Holmes type autono¬mous chaotic oscillator is described. In comparison with the well-known non-autonomous Duffing-Holmes circuit it lacks the external periodic drive, but includes two extra linear feedback subcircuits, namely a direct positive feedback loop, and an inertial negative feedback loop. SPICE simulation and hardware experimental results are presented.
