Hyperchaos from two coupled Wien-bridge oscillators: Research Articles

This paper proposes a simple inductorless approach to generating hyperchaos by coupling two Wien-bridge oscillators with a resistor and a diode. The whole circuit is investigated both numerically and experimentally. Also, its hyperchaotic dynamics is studied theoretically by a topological horseshoe with two-directional expansions which provides an immediate evidence of hyperchaos.
