| Abstract: | Based on the generation mechanism of chaotic attractor,a new three-dimensional multi-scroll chaotic system is proposed by introducing a unit sawtooth wave function to modify the chaotic Colpitts oscillator model,from which a(2K+1)-scroll chaotic attractor is generated.The introduction of the unit sawtooth wave function can produce index-2 equilibrium points of the system,from which multi-scroll attractor is evolved.By using conventional dynamical analysis methods,the dynamical behaviors of the proposed mult... |
