摘要

为实现铁矿石烧结过程中烧结终点和混合料槽料位两个关键参数的综合优化，提出了一种基于模糊满意度的多目标优化控制方法。首先，通过综合运用模糊控制、预测控制的切换控制技术，建立烧结终点的智能优化控制模型;其次，为稳定混合料槽料位，基于专家知识，建立了混合料槽料位专家控制模型;最后通过构造求解多目标优化问题的系统满意度函数，将多目标优化问题转化为单目标优化问题，求取系统的满意解，实现烧结过程多目标优化控制。仿真结果和实际运行结果表明提出的方法是可行而有效的。

Abstract

In the iron ore sintering process，to optimize two key parameters，the burning through points and the bunker-level，an multi-objective optimal control method is presented based on fuzzy satisfactory degree.First，an intelligent optimal control model of the burning through points is established by using fuzzy control，predictive control and switching control strategy.Next，an expert control model is designed for the bunker-lever.Finally，the satisfactory-degree function of the system is designed to obtain satisfactory solutions，which transforms the multi-objective optimization problems into the single-objective optimization problems and eventually results in multi-objective control of the sintering process.Results of simulation and actual runs show that the proposed method is feasible and effective.
