Analogue electrical circuit for simulation of the Duffing-Holmes equation. (English) Zbl 1245.94115

Summary: We describe an extremely simple second-order analog electrical circuit for simulating the two-well Duffing-Holmes mathematical oscillator. Numerical results and analog electrical simulations are illustrated with the snapshots of chaotic waveforms, with the phase portraits (the Lissajous figures) and with the stroboscopic maps (the Poincaré sections).
