摘　　要：以Chua系统为典型实例,利用数字化处理技术,对其连续时间混沌系统的状态方程进行离散化。基于FPGA实验平台中的DSPBuilder技术,设计了Chua系统的MDL源文件,阐述了用FPGA技术产生Chua混沌吸引子的设计原理、方法与实验步骤。在此基础上进行了电路实验,给出了硬件实验结果,证实了数值仿真与硬件实验结果的一致性。该方法还可适用于在广义Lorenz系统族中产生混沌吸引子。With Chua system as a typical example and by using digital processing technology, the state equation of continuous time chaotic system is discretized. Based on DSPBuilder technology in FPGA experimental platform, the source document of Chua system is designed. The design principle, method and experimental procedure are discussed. On this basis, the circuit experiment is carried out and the hardware experimental result is given. All this confirms the consistency of numerical simulation and hardware experimental result. This method could be applied in generating chaotic attractors in gneralized Lorenz system family.
