摘要
研究新四维超混沌系统的自适应滑模同步问题.针对整数阶及分数阶新四维超混沌系统,分别给出控制律和滑模函数设计的方案,得到新四维超混沌系统取得自适应滑模同步的充分条件.研究结果表明,在一定条件下,新四维超混沌系统能取得自适应滑模同步,数值仿真结果验证了方法的有效性.
This paper is concerned with adaptive sliding mode control synchronization problem for new four-dimensional hyper-chaotic systems.For the new four-dimensional superchaotic system of integer order and fractional order,sliding mode functions are introduced and control laws are designed.The sufficient conditions for adaptive sliding mode synchronization of the new four-dimensional chaotic system are obtained.The results show that the adaptive sliding mode synchronization for the new fourdimensional chaotic system can be achieved under certain conditions.A numerical simulation is presented to demonstrate the effectiveness of the proposed scheme.
