【摘要】An improved hyper-chaotic system based on the hyper-chaos generated from Chen's system is presented, and some basic dynamical properties of the system are investigated by means of Lyapunov exponent spectrum, bifurcation diagrams and characteristic equation roots. Simulations show that the new improved system evolves into hyper-chaotic, chaotic, various quasi-periodic or periodic orbits when one parameter of the system is fixed to bca certain value while the other one is variable. Some computer simulations and bifurcation analyses are given to testify the findings. 【总页数】7页(84-90) 【关键词】
