摘要
用一个统一系数的含非线性项代替蔡氏电路中线性和非线性部分的方法构造一种变形蔡氏电路,通过理论分析、计算机仿真实验两种方法,研究该电路平衡点的稳定性、初值敏感性质、通向混沌的道路,结果证明该系统是双涡卷吸引子混沌系统。用外力反馈控制方法对该混沌系统进行控制,理论分析和计算机仿真结果表明,该变形蔡氏电路在外加控制作用下,只要取适度的反馈控制强度信号,即可将该混沌系统控制到稳定的周期态,实现预期控制目标。
This paper studies a new modified Chua＇s circuit,which linear and nonlinear parts is taken the place by a unified coefficient. Both theoretical analysis and computer simulation experiment are made to test its＇ stability of equilibrium point of the circuit、initial value sensitivity properties and the road leading to chaos. The result shows that the system is the double scroll chaotic system. Controlled by the force feedback,the chaotic system can be controlled to a periodic state stability as the desired control objectives so long as the moderate-intensity feedback control signal is obtained.
