本文采用单变量的比例微分反馈法实现了对多涡卷Chua电路的混沌控制。理论分析和系统仿真结果表明:取不同的控制参数,可实现将多涡卷Chua电路控制到系统原有的不稳定第一类不动点,同时,通过这种控制策略,也可使该电路系统产生Hopf分岔,得到1p、2p、4p和8p稳定的周期轨道。由于这种控制方法只需单个状态变量对系统的一个子系统进行反馈就可实现混沌控制的
In this paper, the single-variable proportional-derivative feedback method is used to realize the chaos control of multi-scroll Chua circuit. The theoretical analysis and system simulation results show that taking the different control parameters, the multi-scroll Chua circuit can be controlled to the original instable first-class fixed point of the system. At the same time, through this control strategy, the circuit The system produces Hopf bifurcation and obtains 1p, 2p, 4p and 8p stable periodic orbits. Because this kind of control method only needs a single state variable to feedback to a subsystem of the system, can realize the chaotic control
