TY - JOUR T1 - Approach to approximate distribution reduct in incomplete ordered decision system AU - JO - Journal of Information and Computing Science VL - 3 SP - 181 EP - 188 PY - 2024 DA - 2024/01 SN - 3 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jics/22768.html KW - anti-synchronization KW - four-dimensional autonomous system, active control. AB - This paper analyzed the anti-synchronization of the four-dimensional autonomous different structural hyperchaotic systems, and achieved the anti-synchronization of the hyperchaotic Lorenz-Chen system, hyperchaotic Chen-Lü system and hyperchaotic Lü-Lorenz system with each other via the active control theory. Numerical simulations are provided for illustration and verification of the proposed method.
