中文摘要： 动态过程优化问题在化工过程优化中广泛存在。该问题的求解对节约能源与环保都具有重要意义。但实际问题建立的模型，解析法一般无法解决这类问题。因此，寻找数值方法求解此类问题具有理论与工程应用意义。本项目从计算机控制的角度出发，研究在利用群智能算法求解此类问题的过程中所存在的一些关键性问题。研究的主要内容包括：（1）分析如何结合化工优化问题的特点与群智能算法的特点，提出更有效的算法；（2）分析如何克服利用群智能算法求解此类问题在对控制变量进行离散化时所带来的高维优化问题；（3）研究如何通过大量的测试，对智能算法的优化特性进行分析，进而对化工优化模型分类；（4）将所得的算法用于：管式反应器的温度最优分布、连续搅拌釜式反应器动态优化、Park-Ramirez 生物反应器补料流率的动态优化等具体实际模型。项目的工作对化工过程优化问题的求解研究、优化理论及算法都具有促进作用。

英文摘要： Dynamic process optimization problems are common in the chemical process optimization. It is meaningful for energy conservation and environmental protection to solve the problem. But analytical method generally can't solve the real problem model. So the numerical algorithm to study such issues is an important research subject; At the same time, from the perspective of computer control, we just need to know the value of the control quantity at different time. Therefore, it has the significance of theory and engineering applications for the numerical method. This research explores some key issues existed in the process of using swarm intelligence method for this kind of issues. It includes: (1) Analysis of how to combine the characteristics of the chemical engineering optimization problem and the characteristics of swarm intelligence algorithm, put forward a more effective way; (2)How to deal with the high-dimensional optimization problems when using swarm intelligence method for solving such problems in the discretization of control variables; (3) Study the influence of the different test functions for the Optimization features of different intelligence algorithms by a large number of test, and realize to Classify chemical optimization models;(4)Apply the algorithm into practical models such as optimum distribution of the temperature of the tubular reactor, dynamic optimization of continuous stirred tank reactor, dynamic optimization of the feed-rate of Park-Ramirez bioreactor .The project have significance on optimization theory and algorithm, solutions to the chemical process optimization problems.
