Research on Calculation Method of Check-sluice Discharge Based on PSO-SVM Model

摘要: 为了进一步提高节制闸过闸流量的计算精度，提出了一种基于PSO-SVM 模型的过闸流量计算方法。分析了PSO-SVM 模型的计算原理和方法，并用某节制闸一年的水文实测数据对PSOSVM 模型进行了训练与计算，结果表明：PSO-SVM 模型用于节制闸过闸流量计算，具有较高的计算精度。但在实测样本较少时或流量较大的区间内，模型表现欠佳。

Abstract: In order to improve the calculation accuracy of check-sluice discharge, a calculation method of discharge based on PSO-SVM model is proposed. The calculation principle and method of PSO-SVM model are analyzed. The hydrologic data of a check-sluice for one year are used to train and calculate the PSOSVM model. The results showed that the PSO-SVM model could be used to calculate the check-sluice discharge and had high calculation accuracy. However, when the measured samples are not enough and the discharge is large, the performance of the model is poor.
