改进的正弦混沌系统及性能分析
Improved Sinusoidal Chaotic System and Performance Analysis
摘要
Abstract
Aiming at the shortcomings of the robustness,complexity and unpredictability of Tent-Sine chaotic maps construct?ed based on sinusoidal chaotic systems,a delay chaotic map of Tent-Sine chaos is proposed. Firstly,the output of the existing Tent map and Sine map are linearly weighted and combined,then the transformation of sine function is performeded on this combination results,and the Tent-Sine chaotic map is generated. Secondly,the generated Tent-Sine chaotic maps are respectively performed from one to eight units of delay processing,the chaotic map after delay is obtained,and finally the bifurcation diagram,sample en?tropy,Kolmogorov entropy are tested and analyzed. The experimental results show that the proposed delayed Tent-Sine chaotic map has a larger chaotic range than the undelayed. The sample entropy of the delayed two-unit Tent-Sine chaotic map is greater than the original undelayed,delayed other units of the maps,and the Kolmogorov entropy of the two and three units of the Tent-Sine chaotic maps are more stable. Therefore,the proposed delayed Tent-Sine chaotic map is more robust,more complex,and has better unpre?dictability.关键词
