热处理炉钢板温度度的的自适应混沌粒子群算法–最小二乘支持向量机优化预报算法
Optimized prediction algorithm with adaptive chaos particle swarm optimization-least squares support vector machine for steel plate temperature prediction in heat treatment furnace
摘要
Abstract
To deal with the difficulty in parameter adjustment and the low precision of the traditional heat-conduction model, we build a prediction model for the steel plate temperature, based on the least-squares-support-vector machine(LSSVM) which is optimized by the improved particle-swarm algorithm. First, on the basis of the particle-swarm algorithm, we propose an adaptive chaotic particle-swarm algorithm(ACPSO) for which the validity, robustness and the optimization efficiency are quantitatively evaluated based on performance indices; and then, the radial basis functions are selected as the kernel function. Thus, the temperature prediction model of steel plate is built with LSSVM and optimized with ACPSO algorithm. Finally, the model is simulated by using the data acquired from the site and used in practical operation; the result indicates that the prediction model based on ACPSO and LSSVM has higher prediction accuracy than the tradition one, achieving the goal of intelligent optimization.关键词
