摘要
混沌系统在振荡过程中可以产生一系列的能量交换,能量的大小取决于系统的混乱程度。基于能量交换与系统混沌振荡之间的关系,设计了一个含有荷控忆阻器的混沌电路。根据亥姆霍兹定理,计算出该混沌电路的Hamilton能量,研究了电路在电感充放电时的能量变换。利用Hamilton能量作为电路的一个控制项,可以控制电路在不同的状态,调节该控制项的反馈增益,可以有效地控制系统的混沌吸引子到期望状态。仿真结果表明,该控制方法可以有效控制系统的混沌态。
Chaotic systems can produce a series of energy exchanges during the oscillation,and the amount of energy depends on the degree of chaos in the system.Based on the study of the relationship between energy exchange and system oscillation,a chaotic circuit with a load⁃commanded memristor was designed.According to Helmholtz's theorem,the Hamilton energy of the chaotic circuit is calculated,and the energy transformation of the circuit is studied when the inductor is charged and discharged.By using Hamilton energy as the control of the system,the feedback gain of the command is adjusted through emulation,and the system is effectively controlled.The emulation results show that this command method can effectively control the chaotic state of the system.
