中文摘要： 矿渣微粉一种新型的绿色环保型建材产品，具有耐腐蚀、粘结力强、强度高、防微缩等特点。微粉生产不但能够使矿渣得到有效回收和利用，还能给企业带来可观的经济效益，目前已经成为钢铁企业的一个重要的生产环节。由于是新兴产业，当前微粉生产过程的控制系统很难达到全流程的优化控制，常常出现产量底、成本高、控制系统故障，甚至控制系统失效的等问题。本项目全面了解微粉生产的背景和工艺，仔细分析不同空气流动情况下微粉颗粒的运动规律，认真研究微粉生产过程的主要控制量、被控量之间的函数关系，各种环境参数（如湿度、温度、原料成分等）对微粉质量的影响；基于大量的现场测量数据，构建系统等价的黑箱或灰箱模型；在满足控制量物理约束情况下，构建有效性能指标，针对基于不同函数基底描述的系统模型设计最优控制器，提高控制品质；综合考虑微粉生产的各种工况、生产成本和利润、能源消耗等多个因素，构成微粉生产全流程优化控制系统。

英文摘要： Slag powder is a new type of green building materials products, has the characteristics of corrosion resistance, strong adhesion, high strength and anti scaling. Powder production can not only make slag recovery and utilization, but also bring considerable economic benefits to the enterprise, has become an important production process of iron and steel enterprises. Because it is a new industry, the current control system of powder production process is difficult to give the optimal control of the whole process, often yields low production, high cost, control system fault, even the control system failure etc.. This project will try to give a comprehensive understanding of powder production background and process, careful analysis of movement of slay particles in different air flow condition, serious study of the function relationship among the main control and controlled quantity in powder production process, and the influence of various environmental parameters (such as humidity, temperature, composition of raw material etc.) on the powder quality; a large number field measured data will be used to construct the system equivalent black or grey box model; under the satisfaction of physical constraints, an effective performance index and the optimal controller based on the different model described by different base function will be set up to improve the control quality; comprehensive consideration of various conditions of powder production, production cost and profit, energy consumption and other factors has been made, an optimal control system of slay powder production process will be given.
