中文摘要：
提出利用Logistic混沌映射调制Unified混沌系统的参数,构建Logistic-Unified（LU）混杂混沌系统的思想.在Logistic混沌映射产生的随机数值的调制下,Unified混沌系统的参数随机变化,控制LU混杂混沌系统在广义Lorenz系统、Lü系统和广义Chen系统间随机切换,产生极其复杂的混沌信号.用数字信号处理（DSP）芯片对LU混杂混沌系统进行硬件实现,硬件实验与数值仿真结果一致,证明了理论分析的正确性.
英文摘要：
A Logistic-Unified hybrid chaotic system is generated. In this system,following the random changing of the state variable values of the Logistic map,the parameter values of the Unified system can be modulated randomly,and the Logistic-Unified hybrid chaotic system can be switched between the generalized Lorenz system,Lü system and generalized Chen system randomly. The extremely complicated chaotic signal is generated via the Logistic-Unified hybrid chaotic system. The Logistic-Unified hybrid chaotic system is realized based on digital signal processing （ DSP ）. Hardware experiments and software simulation are completely consistent,and the results demonstrate the validily of the theoretical analysis.
