Analysis and Circuit Implementation of a Three-Wing or Four-Wing Chaotic Attractor

The paper firstly analyzes a three-wing or four-wing chaotic attractor which is reported recently. When vary, the dynamics of the chaotic attractor are very complex, not only can the three-wing or four-wing chaotic attractor be observed by numerical simulation, but also some typical periodic attractors can be found. In addition, an analog circuit is also made for the three-wing or four-wing chaotic system, and the results of circuit experiment observed by oscillation are well coincided with those of simulation. Furthermore, the chaotic characteristics of the three-wing or four-wing chaotic system are verified physically.
