摘要
文氏桥电路是典型的振荡器,在文氏桥电路上增加非线性元件,可构成混沌系统。为使电路产生混沌,根据文氏桥振荡电路的特点,通过电路中参数的调节,使用切换控制法,使系统状态方程变为三维,在三维空间中,该系统产生了混沌。然后通过增加滞回切换控制电路,使文氏桥式振荡器产生了双涡卷和单涡卷的混沌现象。通过串联电阻和二极管,将两个文氏桥振荡器耦合在一起,实现文氏电路的混沌化设计。
Wien-bridge circuit is a typically RC circuit.When you install a nonlinear element on it,they will constitute a chaotic system.Based on the characteristics of Wien-bridge circuit,through adjusting the parameters of circuits and using the switch-over control method can let the system equations into three-dimensional.In this status,the system will create the chaotic Wien-bridge circuit.Then by increasing the hysteretic switch-over control system,let Wien-bridge circuit generates phenomena of Binary Vortex and Single Vortex.Finally,through the series and parallel circuits and the diode,two Wien-bridge circuits can be coupled together that the design of chaotic Wien-bridge circuit can be completed.
