摘要:分布式控制系统具有系统构成灵活、操作管理便捷、控制功能丰富、信息资源共享、安装调试方便等特点，所以在现在科学研究和工业生产中得到了越来越广泛的运用。

　　　本文首先通过做简单控制和复杂控制实验，熟悉操作过程和丰富知识。在此基础上，完善缺省和部分不准确实验数据，使得数据更有参考价值。本文创新点在于研究时滞特性对液位和温度的影响，运用史密斯（Smith）预估算法，改善大时滞系统的控制品质。

　　　最后在A3000实验系统上进行实验研究，给出了相关数据波形并进行分析，结果验证了设计的可行性和控制效果的品质。总结简单控制、复杂控制和研究性控制三部分实验，编写提交实验指导书、创建的组态工程和实验数据。分布式控制系统知识的学习和研究，对自主创新研究奠定基础。对于A3000系统更深入了解和熟练操作。为后面研究提供依据和经验。完善了分布式控制系统的10个基础简单实验和5个复杂实验数据和实验指导。共同建立了5个创新实验研究和指导。

　　　自主研究创新了双容液位传输滞后补偿控制、温度纯滞后大延迟补偿控制研究。都是理论介绍不够深入，实际资料中少有组态设计，更没有组态实验结果的设计。①自己创建组态实验工程一份，②实验指导一本，③实验数据。

Abstract：Distributed control system has the system flexible, convenient operation management, control function, rich information resources sharing, easy installation and debugging, so now in scientific research and industrial production has been used more and more widely.

　　This paper make a simple control and complex control experiment, familiar with the operation process and knowledge. On this basis, improve the default and accurate experimental data, make the data more reference value. This innovation is to study the delay characteristics of liquid level and temperature effects, by Smith ( Smith ) estimation algorithm, to improve the control quality of the system with large time delay.

　　Finally in A3000 experimental system for experimental research, given the relevant data and analysis, the results verify the feasibility of the design and effect of control quality. Summary of simple control, complex control and research of the three portion of the control experiment, drafting experimental guide books, create configuration project and experimental data. Distributed control system of knowledge learning and research, on the basis of independent innovation. For  the A3000 system more in-depth understanding and skilled operation. In order  to provide the basis for the study and experience. Improvement of  distributed control system based on 10simple experiments and 5 complex experimental data and guidance. Jointly established  in 5 innovative experimental research and guidance.

　Independent research and innovation of the double level transmission delay compensation control, temperature of pure lag compensation control of large delay. All theory is not deep enough, the actual data is rare in configuration design, no configuration results of experimental design. Create your own configuration of experimental project a, II experimental guide book, the experimental data.
