非周期间歇控制下随机复杂网络的均方指数相继滞后同步

Mean square exponential successive lag synchronization of stochastic complex networks under aperiodically intermittent control

  • 摘要: 在自然界和工程问题中,相继滞后同步是一种重要的同步现象。控制理论有很好的经济实用价值,尤其是间歇控制理论,且以往对相继滞后同步的研究从未考虑过噪声的影响,因此,用间歇控制研究含噪声的复杂动力学网络相继滞后同步很有必要。为得到模型的同步条件,首先建立一个具有噪声扰动的分布式线性耦合的复杂动态网络模型;设计间歇控制器,保证控制信号不是在整个区间上被激活,而是只在控制子区间上被激活,从而使受控网络达到期望的状态;在受控网络的基础上,解析地推导出保证相继滞后同步均方稳定的充分条件;将设计的间歇控制策略应用到蔡氏电路等实际系统中,检验理论结果的准确性。数值模拟结果验证了理论结果的正确性和有效性。

     

    Abstract: In nature and engineering problems, successive lag synchronization is an important synchronization phenomenon. Control theory has good economic and practical value, especially the intermittent control theory. In addition, the influence of noise has never been considered in previous studies on successive lag synchronization. Therefore, it is necessary to study the successive lag synchronization of complex dynamic networks with noise by using intermittent control. In order to obtain the synchronization conditions of the model, firstly, a distributed linear coupling complex dynamic network model with noise disturbance was established. Secondly, an intermittent control was designed to ensure that the control signal is not activated in the whole interval, but only in the control subinterval, thus to make the controlled network reach the desired state. Based on the controlled network, a sufficient condition was derived analytically to ensure the mean square stability of successive lay synchronization. Finally, the intermittent control strategy was applied to Chua's circuit and other practical systems to test the accuracy of the theoretical results.Numerical simulation results verify the correctness and validity of the theoretical results.
