近年来，我国科学技术的发展越来越快，各行各业的技术化水平越来越高，当然农业也不例外。诸多农场都引入了各种各样高新技术来提高自己的生产效率。在使用马铃薯生产淀粉时，一种全新的控制系统被引入，其名为预测控制系统，这套系统非常先进，能够发挥相当重要的作用，但是其对本身淀粉的生产线的各项要求非常之高，所以想要完美运行还是有些困难的。所谓预测控制系统，其实质上就是一种利用高科技手段将风险提前预知后预测，将需要管理的项目集中管理的系统，前文已经提到，其运行离不开整个生产线的各方面要求，而最大的要求就是拥有一套完善的监控系统。在监控系统中，PLC和工控机和实时机分别承担着不同的监控任务，三者互相协调配合才能够完成整个监控工作，其中PLC的稳定性与计算机的运算速度是决定整个监控系统能力的关键所在。
本文的研究对象是位于我国东北地区的某个大型农场，此农场在淀粉生产方面有着相当丰富的经验且已经拥有了属于自己的一条极为成熟的马铃薯淀粉生产线，本文基于此背景下对此农场的马铃薯淀粉生产线进行深入的分析研究，旨在结合此农场的具体情况开发一套与之相适应的预测控制系统。预测控制系统功能十分完善，其不仅能够对整个淀粉生产过程实施全程监控，还能够对生产过程中的各项数据进行实时精准测量和控制，这样优秀的管控能力能够使生产线生产效率大大提高，变相提高了经济效益的同时还保障了产品的质量，提升了产品带来的社会效益。由于此系统是针对农场马铃薯生产线开发的，所以其要实行的管控基本都是以流程和时间为要素的，所以在选择预测控制方法时应该选择以PLC为基础的控制方法。之后再对研究对象进行进一步分析，结合其特点在系统设计时再加入一种先进的自动化控制体系-罗克韦尔自动化软硬件体系。在确定了控制方法及体系后，整个控制系统已经初步成型，其对整个马铃薯淀粉生产线的控制效果也已经可以预见，那就是全程自动化地管控。本文在对此大型农场马铃薯淀粉生产线作介绍时，重点放在了其软硬件组成、运行原理、以及基于其开发而来的预测控制系统的设计思路与最终结构，在上述三者介绍完后又对在线控制器的设计过程与组成作了详尽的介绍而最后介绍的是PID参数，通过对此参数的深入研究与分析基本实现了将其融入到预测控制系统的原定目标。基于此大型农场马铃薯淀粉生产线的预测控制系统的开发是非常成功的，并且这套系统开始投入到实际的生产当中，取得的效益也是有目共睹的，可以说本文的研究还是具有实际价值的。
ABSTRACT
In recent years, the development of science and technology and faster, all walks of life of the increasingly high level of technology, and agriculture is no exception. Many farms have introduced a wide range of high technology to improve their productivity. When you are using starch potato production, a new system was introduced, its predictive control system, this system is very advanced, can play a very important role, but the requirements for their own production line of starch is very high, so I want to run perfectly is somewhat difficult. So-called prediction control system, which is essentially a high-tech means to spread risks after the advance will require centralized management of project management systems, as mentioned before, various requests of its performance can not be separated from the whole production line, while the maximum requirement is to have a comprehensive monitoring system. Monitoring systems, PLC and IPC undertakes different monitoring tasks and real time respectively, and in co-ordination of the three to complete the monitoring work, of which PLC is to determine the stability and speed of the computer where the key to the whole monitoring system.
Paper of research object is is located in China northeast of a large farm, this farm in starch production aspects has quite rich of experience and has has has belongs to himself of a article extremely mature of potato starch line, paper based on this background Xia on this farm of potato starch line for in-depth of analysis research, aimed at combines this farm of specific situation development set and of phase adapted of forecast control system. Features a comprehensive predictive control system, which can not only monitored the starch production process as a whole, but also on the production process of precision measurement and control data in real-time, so that excellent ability to manage and control can make the production much more efficient thus improve economic efficiency at the same time guarantees the quality of products, and social benefits of improved product. Because this system is developed for farm potato production line, its control should be implemented is based on the basic elements of processes and time for, so when selecting a predictive control method based on PLC control method should be chosen. Study after further analysis, combined with its features at system design time and then adding an advanced automated control systems-Rockwell Automation hardware and software systems. After you determine that the control method and system, the control system has initially taken shape and its control effect of potato starch production line as a whole has been predictable, that is full automatic control.Paper in on this large farm potato starch line made introduced Shi, focus put in has its hardware and software composition, and run principle, and and based on its development and to of forecast control system of design ideas and eventually str
