摘要
文章分析了典型电路的混沌演化过程。在简谐激励下,将压电谐振器等效为电压源和电容,再串联线性电感、电阻和非线性电容,构建了一个Holmes型Duffing电路。基于Kirchhoff定律,建立了电路的状态方程。仿真结果表明,建立的Duffing电路具有丰富的动力学行为,调整参数可使电路进入混沌状态。
The chaotic evolution processing of typical circuits is analyzed.Under a harmonic excitation,the piezoelectric resonator that is equivalent to a voltage source and a capacitor is connected with a linear inductor and a nonlinear capacitor in series to construct a Holmes-type Duffing circuit.Based on Kirchhoff's law,the state equation of the circuit is established.The simulation results show that the Duffing circuit presents dynamical behaviors,moreover,and the system can evolve into chaotic state by adjusting the parameters correctly.
