摘要
搭建了基于模拟电感的蔡氏电路,通过改变分岔参量,得到了基于模拟电感的蔡氏电路经倍周期分岔走向混沌的相图.实验结果表明,相对于原始蔡氏电路,基于模拟电感的蔡氏电路的分岔参量调节范围更宽,倍周期分岔现象更为丰富,且易起振,便于集成.
Chua＇s circuit based on analog inductor was constructed.By adjusting bifurcation parameters in analog inductor-based Chua＇s circuit,phase portraits from period-double bifurcation to chaos were obtained.Experimental results showed that compared with original Chua＇s circuit,the parametric range of bifurcation was much wider,the phenomena of bifurcation were more abundant in analog inductor-based Chua＇s circuit.The circuit based on analog inductor was easier to oscillate and integrate.
