近期文献中报道了在具有自适应反馈突触的神经元模型中,随着参数的变化,存在从两个共存吸引子到一个相连吸引子再到两个共存吸引子的混沌转化现象.本文对此模型进行了电路设计,同时对具有非单调激活函数功能的电路设计进行了细致的研究,并利用Electronic Workbench(EWB)软件对所设计的电路进行了仿真实验,研究了电路中的混沌现象,验证了所设计电路的动力学行为与通过数值模拟结果十分相似.
Recent literature reports that in a neuron model with adaptive feedback synapses, the chaos transformation from two coexistent attractors to one connected attractor to two coexisting attractors exists as the parameters change. The circuit design of this model was carried out. At the same time, the circuit design with non-monotonic activation function was studied carefully. The electronic circuit was simulated by Electronic Workbench (EWB) software. The chaos in the circuit was studied, It is verified that the dynamic behavior of the designed circuit is very similar to that obtained by numerical simulation.
