混沌系统局部控制方法的一种新途径

A new approach of the partial control method in chaotic systems

Rubén Capeáns, Juan Sabuco, Miguel A. F. Sanjuán

摘要:

本文提出了一种新的部分控制方法,它是一种适用于受有界噪声影响的瞬态混沌动力学的有效控制技术。通常,我们希望避免这些混沌瞬态逃逸到相空间的某个区域$Q$之外。为此,存在一个控制界限,使得对于小于该界限的控制,轨迹保持在称为安全集的$Q$的特殊子集中。这种新方法的目的是更进一步,为$Q$的每个点计算使其保持在$Q$中的最小控制界限。这定义了一个特殊的函数,我们称之为安全函数,它可以提供必要的信息来计算安全集,一旦我们选择了一个特定的控制界限值。这提供了一种通用的方法,其中包括以前已知的情况,并且其使用涵盖了更多样化的场景。

英文摘要:

We present here a new approach of the partial control method, which is a useful control technique applied to transient chaotic dynamics affected by a bounded noise. Usually we want to avoid the escape of these chaotic transients outside a certain region $Q$ of the phase space. For that purpose, there exists a control bound such that for controls smaller than this bound trajectories are kept in a special subset of $Q$ called the safe set. The aim of this new approach is to go further, and to compute for every point of $Q$ the minimal control bound that would keep it in $Q$. This defines a special function that we call the safety function, which can provide the necessary information to compute the safe set once we choose a particular value of the control bound. This offers a generalized method where previous known cases are included, and its use encompasses more diverse scenarios.
