摘要
研究以x|x| 非线性函数取代折线非线性v_i特性后的蔡氏电路 .重点讨论非线性函数x|x| 对于产生混沌振荡的作用 ,并用Shil’nikov方法给予严格的证明 .用计算机模拟对电路中发生的分岔过程进行了分析 ,并对在实验室实现这种非线性函数的实际蔡氏电路设计作了描述 .
A modified Chua's circuit is investigated by replacing its piecewise linear \$v i\$ characteristic of the nonlinear component with the \$x|x|\$ function. The role of the function \$x|x|\$ as a chaos generator is discussed, and is rigorously verified via the Shil'nikov method. Simulations with bifurcation analysis are carried out and, finally, a circuit design implemented in laboratory is described.\;
