混沌系统参数扰动方案及分析.

Perturbation of chaotic system can effectively solve the degradation of chaotic system dynamic characteristics caused by computer finite precision effect. This paper proposed parameter perturbation scheme for digital chaotic system based on the construction method of Cantor set in interval mapping. This scheme spread the sequence values obtained from each iteration of chaotic system proportionally to the compressed interval of chaotic state parameters, so as to achieve the purpose of disturbing chaotic sequence. The experimental simulation and analysis show that the chaotic system with disturbance has better chaotic characteristics, larger parameter range and higher complexity. [ABSTRACT FROM AUTHOR]
