Generalized reduced-order synchronization of chaotic system based on fast slide mode 总被引:1,自引:0,他引:1 下载免费PDF全文
A new kind of generalized reduced-order synchronization of different chaotic
systems is proposed in this paper. It is shown that dynamical evolution of
third-order oscillator can be synchronized with the canonical projection of
a fourth-order chaotic system generated through nonsingular states
transformation from a cell neural net chaotic system. In this sense, it is
said that generalized synchronization is achieved in reduced-order. The
synchronization discussed here expands the scope of reduced-order
synchronization studied in relevant literatures. In this way, we can achieve
generalized reduced-order synchronization between many famous chaotic
systems such as the second-order D\"{u}ffing system and the third-order
Lorenz system by designing a fast slide mode controller. Simulation results
are provided to verify the operation of the designed synchronization. 相似文献

近江牡蛎受精细胞学研究 总被引:5,自引:0,他引:5
用醋酸──地衣红染色的方法对近江牡蛎人工授精的卵子减数分裂和受精过程进行了详细的细胞学观察.精子入卵前,卵子处于第一次减数分裂的前期(胚泡期),精子入卵后,胚泡消失,然后进行两次减数分裂,在海水温度为28.8℃的情况下,授精后33min和45min,绝大部分受精卵已排出第一极体和第二极体,雄原核可在第一极体排出后及第二极体排出前任何时期内形成,雌雄原核以联合的方式将两组染色体合并,授精后1h,大部分卵子完成第一次卵裂.在25℃和26℃授精的情况下,观察到了较多的多精入卵的现象.卵子发育的非同步性现象非常明显. 相似文献

Synchronization between two different noise-perturbed chaotic systems with unknown parameters 下载免费PDF全文
In this paper, a general method of synchronizing noise-perturbed chaotic systems with unknown parameters is proposed. Based on the LaSalle-type invariance principle for stochastic differential equations and by employing a combination of feedback control and adaptive control, some sufficient conditions of chaos synchronization between these noise-perturbed systems with unknown parameters are established. The model used in the research is the chaotic system, but the method is also applicable to the hyperchaotic systems. Unified system and noise-perturbed RSssler system, hyperchaotic Chen system and nolse-perturbed hyperchaotic RSssler system are taken for illustrative examples to demonstrate this technique.[第一段] 相似文献

Chaotic Synchronization of the Master Slave Chaotic Systems with Different Structures Based on BANG-BANG Control Principle 下载免费PDF全文
We propose a Bang-Bang control scheme that can synchronize master-slave chaotic systems. The chaotic systems considered here are structurally different from each other. Different from some control strategies reported previously, the scheme proposed here can be taken as a general one that is independent of the chaotic system itself. 相似文献

We employ several simple numerical experiments to show that the statements that short mean path length or low heterogeneity enhances synchronizability in complex networks could be misleading. Furthermore, we point out that the impacts of the structural parameters on the synchronizability are complicated even if we could change one structural parameter independently. 相似文献

In this paper, a systematic and powerful scheme is proposed to address a generalized-type synchronization of a class of continuous-time systems, which includes generalized lag synchronization, generalized anticipated synchronization, and generalized synchronization. The presented scheme is used to investigate the generalized-type synchronization of the 4D hyperchaotic oscillator and the hyperchaotic oscillator with gyrators. Numerical simulations are used to verify the effectiveness of the proposed scheme. The scheme is more powerful than the scalar signal scheme due to Grassi and Mascolo. 相似文献
