Experimental Design of A Chua’s Chaotic Circuit

Due to the response of chaotic circuit composed of discrete devices is affected by circuit parameters and the initial state of energy storage elements, the instability of inductance parameters may bring uncontrollable problem of circuit chaos. On the basis of introducing the dynamic principle of Chua’s chaotic circuit, this paper uses simulated inductor to replace the passive independent inductor, carries out the simulation based on Multisim software, and obtains the phase trajectory diagram of the improved Chua’s circuit. The experimental circuit, fabricated by single panel etching process, achieves the same experimental results with the simulation results, thus verifying the effectiveness of the simulated inductor. The improved chaotic circuit can be used as an expanded teaching case of circuit experiment to improve students’ enthusiasm in learning circuit and electronic technology courses, thereby enhancing their understanding of chaotic theory.
