摘　　要：以Lorenz系统为研究对象,开展Lorenz系统的电路模块化设计,并利用Multisim软件完成模拟仿真;然后基于Altium Designer软件进行Lorenz系统的原理图设计及印刷电路板绘制;最后利用运算放大器、电阻及电容等元器件完成系统的印刷电路硬件电路板焊接与实验,从示波器观测的测试波形图与仿真结果一致,表明了该硬件电路设计的合理性与可行性。By taking the Lorenz system as the research object,the modular circuit design of the Lorenz system is carried out,and the Multisim software is used to complete the simulation.Then the design of the schematic diagram and printed circuit board drawing of Lorenz system are carried out on the basis of the Altium Designer software.Finally,the welding and experiment on the printed circuit hardware board of the system are completed by using the components such as operational amplifier,resistance,capacitance,etc.The test waveform diagram from an oscilloscope is consistent with the simulation result,which shows the rationality and feasibility of the design of the hardware circuit.
