基于泡沫尺寸随机分布的铜粗选药剂量控制
Reagent Dosage Control Based on Bubble Size Random Distribution for Copper Roughing
摘要
Abstract
A bubble size distribution (BSD) based reagent dosage control method is proposed to stabilize the indices and improve the utilization of mineral resources in copper roughing flotation. Firstly, in order to characterize the bubble size structure with non-Gaussian feature, a B-spline estimator is investigated to depict the BSD. Since the weights of B-spline are interrelated with each other and related to the reagent dosage, a multi-output least square support vector machine (MLS-SVM) is hence used to establish their dynamical relationship between B-spline weights and reagent dosage. Finally, an entropy based optimization algorithm is constructed to determine the reagent dosage in order to implement the tracking of the given BSD. Simulation and experimental results show the effectiveness of the proposed method, which has been used to stabilize the product indices for copper roughing.关键词
