论文摘要
在本文中,我们报告了混乱的控制和同步,在穆拉利 - 拉克斯曼 - 芝族电路中的混乱。该电路是由现任作者在2013年引入的,基本上是一个非平滑系统的系统,由于它具有磁通控制的活性备忘录作为其非线性元素,因此具有两个不连续性边界。尽管已经使用状态反馈技术对混乱的控制进行了控制,但自适应同步和基于观察者的方法的概念已被用来实现混乱的同步。这两种技术均基于状态空间表示理论,该理论在控制工程领域众所周知。就像我们在此电路上的较早作品一样,我们得出了Poincaré不连续映射(PDM)和零时间不连续映射(ZDM)校正,这两个校正对于实现非平滑系统的真实动态至关重要。此外,我们已经构建了基于观察者和控制器的状态空间表示的规范形式,建立了luenberger观察者,得出了控制器增益向量以实现状态反馈控制,并计算了开关馈电的增益矩阵,并最终执行的参数估计以效应观察者基于自适应同步。我们通过数值模拟获得的结果包括时间情节,相肖像,参数的估计以及误差图的收敛性以及显示完整同步的相位图。
In this paper we report the control and synchronization of chaos in a Memristive Murali-Lakshmanan-Chua circuit. This circuit, introduced by the present authors in 2013, is basically a non-smooth system having two discontinuity boundaries by virtue of it having a flux controlled active memristor as its nonlinear element. While the control of chaos has been effected using state feedback techniques, the concept of adaptive synchronization and observer based approaches have been used to effect synchronization of chaos. Both of these techniques are based on state space representation theory which is well known in the field of control engineering. As in our earlier works on this circuit, we have derived the Poincaré Discontinuity Mapping (PDM) and Zero Time Discontinuity Mapping (ZDM) corrections, both of which are essential for realizing the true dynamics of non-smooth systems. Further we have constructed the observer and controller based canonical forms of the state space representations, have set up the Luenberger observer, derived the controller gain vector to implement state feedback control and calculated the gain matrices for switch feed back and finally performed parameter estimation for effecting observer based adaptive synchronization. Our results obtained by numerical simulation include time plots, phase portraits, estimation of the parameters and convergence of errors graphs and phase plots showing complete synchronization.
