摘要
研究超混沌修正射影同步算法问题。由于修正射影同步不可预测的伸缩矩阵因子能够有效地提高保密通信的安全性,所以它在保密通信中有着非常诱人的应用前景,但是传统的同步射影算法由于较高的计算复杂度,难以得到广泛应用。针对上述问题,提出了一种新的基于超混沌系统修正射影同步算法。该方法首先给出了一个比已知的射影同步更一般形式的新同步,之后采用激活控制方法使两个一致的超混沌系统整体同步。最后算法在基于软件Maple和稳定性理论基础上,通过数值仿真同步的结果表明,提出的算法能够自主选择调节缩放矩阵中的比例因子,可以较好地满足状态控制器设计的射影同步,降低了算法的复杂性。
Study on modified projective synchronization algorithm for hyperchaos.Because modified projective synchronization of unpredictable dilation matrix factor can effectively improve the security of secret communication,so it is in secure communication in a very attractive application prospect,but the traditional synchronous projective algorithm due to the high computational complexity,it is difficult to get the extensive application.In view of the above problems,this paper put forward a new hyperchaotic system based on modified projective synchronization algorithm.The method firstly gave a better known than projective synchronization of a more general form of the new synchronization,after using active control method to make two identical hyperchaotic system overall synchronization.The final algorithm based on software Maple and stability on the basis of the theory,through the numerical simulation results show that the proposed synchronization,the algorithm can choose the regulation of scaling matrix scaling factor,it can better meet the state controller design of projective synchronization,reduces the complexity of the algorithm.
