摘要
提出了一个新的混沌系统,研究了其基本动力学特性.设计了实现该系统的混沌电路,电路实验结果验证了系统的混沌行为.根据Lyapunov稳定性理论,采用自适应backstepping控制方法,把系统控制到一个有界点.数值仿真证明了该方法的有效性和可行性.
In this paper a new chaotic system is presented.Some of its basic dynamical properties are studied.An electronic circuit is designed to realize the new chaotic system.Experimental chaotic behavior of the system is found to be identical to the dynamical properties predicted by theoretical analysis and numerical simulations.Based on Lyapunov stability theory,the new chaotic system is controlled by the method of adaptive backstepping.Numerical simulation shows the feasibility and effectiveness of this approach.
