摘　　要：在现有磁控型忆阻器蔡氏混沌电路研究基础上,用荷控型忆阻器构建了与磁控忆阻器的蔡氏电路成对偶关系的新超混沌系统.动力学研究发现,该系统与磁控型忆阻器蔡氏电路具有一些共性,如平衡点仍是一系列点集,动力学行为除了与电路参数有关外,还极端依赖于电路初始条件,仍存在瞬态混沌和状态转移等奇异非线性现象.还发现一些新特征:在确定电路参数下改变初始值,所出现混沌普遍具有暂态性,最终将演化为稳定周期运动状态;当初始值靠近平衡点的稳定区,系统却呈现截然不同的两种状态.Based on the existing research about flux-controlled memristor Chua＇s chaotic circuit, a new hy- per-chaotic system about charge-controlled memristor is constructed, which is dual to flux-controlled Chua＇s chaotic circuit. A kinetics study has found that the new system shares some characteristics with flux-controlled memristor Chua＇s chaotic circuit. For example, their equilibrium points are an equilibrium point set, their dynamical behavior is not only associated with the circuit parameters, but also closely de- pendent on the initial conditions of the circuit, and some novel nonlinear phenomena, such as the transient chaos and state transitions are present. Some new features have been found, transient chaos is ubiquitous by changing initial value, when parameters of the system are determined, the state of the system eventual- ly evolves into a stable periodic motion state; two orbits are shown in a small area near the stable equilibri- um point.
