基于POD的污染物非均匀浓度场控制方法研究
Study on control method for non-uniform pollutant concentration field based on POD
摘要
Abstract
To address the issue of excessive ventilation energy consumption caused by the assumption of uniform pollutant distribution in industrial ventilation methods,an intelligent ventilation control method based on flow field prediction and traversal optimization is proposed.This method can dynamically regulate the ventilation system according to the needs of target control points.First,proper orthogonal decomposition(POD)is used to reduce the dimensionality and reconstruct the pollutant concentration field,obtaining low-dimensional basis functions and their coefficients;then,basis coefficient interpolation technology is employed to predict dynamic pollutant concentration distributions under different air supply parameters;finally,a traversal optimization algorithm is adopted to search and determine the optimal combination of air supply parameters,which is verified in a two-dimensional air supply parameter space.The results show that the pollutant concentration distribution predicted by this method has a small relative error compared with numerical simulation values,and can accurately predict the concentration field;the optimization algorithm can precisely locate the optimal air supply parameters that meet the requirements,achieving an optimal control error of 0.1%;the running time of the control program in the two-dimensional parameter space is only 78 s,demonstrating the potential of this method for real-time ventilation control.The intelligent ventilation control method proposed in this study provides a new intelligent solution for industrial ventilation,with good applicability and application prospects.关键词
