摘要
将Backstepping方法应用到统一混沌系统的同步控制,通过选择一系列合适的Lyaounov函数,得到了鲁棒性较好的控制器.论证了Backstepping方法也可以使统一混沌系统快速地稳定在平衡点,实现了统一混沌系统的镇定问题.数值仿真说明了基于Backstepping方法设计的控制器可以有效地实现统一混沌系统的同步和镇定控制.
Backstepping mechanism is applied to synchronize unified chaotic systems. A controller with good robust performance is achieved via selecting a series of Lyapunov functions. It is proved that Backstepping method is able to be used to quickly stabilize unified chaos at equilibrium. Simulation results imply that the controller based on Backsteping method can efficiently synchronize and control unified chaotic systems.
