Design And Implementation Of Coking Furnace Intelligent Control System

There are many problems in modern production process, such as multiple variable, nonlinear, environment complication and so on .So ordinary auto-control technology can't satisfy with the need of modern production. With the development of computer control technology, software engineering theory, field bus control technology, intelligence instrument, and network technology, computer is used in a lot of control systems. Computer has higher speed operation capacity, further storage capacity, more effective disposal capacity. So control system combine these advantages and modern control theory and modern software theory can full satisfy with all kinds of environment and require. We can see there are plenty computer is used in industry production process and real-time control process. Directory Digital Control is introduced in the article, and Coking Furnace Intelligent Control System is designed and realized according to DDC. At the same time the development and type of computer control is simple introduced. With development of society and production technology, controlled object becoming more and more complexity. So, if ordinary computer control technology and control theory is used in system, the system is difficult to perfect control complex object. Whereas intelligent control technology can effective dispose complex controlled object. Here, development and content of intelligent control theory are simple introduced. Moreover a kind of digital controller is realized according to intelligent control theory.The design and realize of coking furnace intelligent control system, computer control technology, intelligent control technology, software developing and so on is introduced in the article. And there are six chapters.The first chapter is exordium. Firstly, purport and purpose is discussed. And control scene and environment is introduced. Secondly some theory and knowledge about computer control is introduced. The emphases are knowledge about Directory Digital Control (DDC). We use the blue print in our system. The second chapter is the whole system analysis and design. Firstly, we discuss and analyze the problem of coking furnace pressure. Then we have requirement analysis. Finally, we have whole design according to requirement analysis for the control system. It includes software design and hardware design. Control software including software developing, control arithmetic research and so on. It is emphasis in the article. The third chapter is about design and developing of control software. Analysis, design and some particular realization is introduced in the chapter. The forth chapter is theory and realization of digital controller. Digital control is vital part. Meanwhile, it is also important theory in the article. In the chapter, PID controller, PI controller, Expert-PI controller is researched and intelligent control theory is introduced and discussed.The fifth chapter is about running and debugging of the system in factor environment.The final chapter is result. To summarize computer technology, intelligent control theory. Finally, we summarize the state of whole project and control system.
