Classical three-variable chaotic system coupling synchronization has been implemented in previous work based on DNA strand displacement (DSD). Herein, by using DSD reactions as the foundation, a proportional integral (PI) controller for chaotic system is introduced to realize the hybrid projective synchronization for different four-variable chaotic systems. DSD-based chaotic systems are composed of catalysis modules, annihilation modules and degradation modules for realizing the construction of chaotic attractors. PI controllers are consist of catalysis, annihilation and adjust DSD modules that are easy to modify and can be added to chaotic system for achieving hybrid projective synchronization. Our work can be acted as the reference for the investigation of chaos synchronization.
基于DNA链置换（DSD）的经典三变量混沌系统耦合同步已在先前的工作中得以实现。在此，以DSD反应为基础，引入一种用于混沌系统的比例积分（PI）控制器，以实现不同四变量混沌系统的混合投影同步。基于DSD的混沌系统由用于实现混沌吸引子构建的催化模块、湮灭模块和降解模块组成。PI控制器由催化、湮灭和调节DSD模块组成，这些模块易于修改，可添加到混沌系统中以实现混合投影同步。我们的工作可为混沌同步研究提供参考。
