access icon openaccess Hidden dynamics and multi-stability in an improved third-order Chua's circuit

By utilising an active diode pair to substitute the classical Chua's diode, an improved third-order Chua's circuit is proposed in this study. This circuit has an unstable zero saddle point and two stable non-zero saddle-foci in a local parameter region, from which hidden dynamics and multi-stability are discovered. The parameter region of hidden dynamics is figured out and hidden attractors are captured numerically and experimentally. Furthermore, multi-stability in the proposed circuit are also exhibited by numerical and circuit simulations.
