摘要

本文研究了随机混沌模型所描述的紊流参数值的稳定问题。作为一种基本的控制选项，考虑了基于稳定参数在可接受值(通道)范围内的当前观测值溢出的通道策略版本。在数值实验的基础上，研究了通道控制策略的潜在可能性。结果表明，实现流稳定的主要问题是观测序列的系统分量具有极高的可变性，这是随机混沌的实现。给出了改进的通道控制策略的版本，指出了提高湍流通道稳定技术功能效率的主要方向

STUDY OF THE EFFECTIVENESS OF CHANNEL CONTROL STRATEGIES IN THE PROBLEM OF STABILIZATION OF A TURBULENT HYDRODYNAMIC FLOW

The article considers the problem of stabilizing the value of the turbulent flow parameters described by the stochastic chaos model. As a basic control option, versions of channel strategies based on overrunning of current observations of the stabilized parameter from the range of acceptable values (channel) are considered. On the basis of numerical experiments, the potential possibilities of channel control strategies are investigated. It is shown that the main problem for achieving flow stability is the extremely high level of the variability of the system component of observation series, which is the realization of stochastic chaos. Versions of improved channel control strategies are given, the main directions for increasing the efficiency of functioning of channel stabilization technologies for turbulent flows are indicated
