基于控制Lyapunov函数,对具有不确定参数的Liu混沌系统提出一种同步控制方法,控制律只依赖参数变化范围而不必知道参数的具体数值.与已有结果相比,该设计比较简单,有较强的鲁棒性,能克服较大参数误差对同步的影响.仿真结果说明了所提方法的有效性.
Based on the control Lyapunov function ( CLF), a method of synchronizing chaotic Liu system with uncertain parameters is proposed. The feedback control law presented does not depend on the parameters but on the boundary of the parameters. It shows that the feedback is simple and robust. Simulation studies on Liu chaotic system also verify the effectiveness of the proposed scheme when the parameters vary largely.
