The Studying Of Controll Strategies Of Multi-partment Driving

The multi-partment driving is used very widely, such as paper making, vehicle, and metallurgy and so on, all of these fields use the multi-partment driving. In the multi-partment driving all the partment should be control singly, and yet the relation among partments should be harmonious. The multi-partment driving develop in following aspects large-scaled, high speed, and accurate, at the same time restricted by factors such as tension control. By now, in the equipment making fields, here are large differences between china and the developed countries. The control technique of multi-departments driving take the most important place in the equipment industry, and also is the main factor of the restraining the development of the equipment industry. So researching the controlling strategies of multi-partment driving is very significant. Now the researching on the controlling strategies of multi-partment driving is mainly concentrated on two fields which are the control theory and the control service. However, there little articles about which using the control theory control the apparatus. The control theory is mainly concentrate in such fields as artificial intelligence, adaptive control, expert system, random control and so on.. In the industrial production fields the apparatus mainly include Masters, PLC and DCS and also the control system made by themselves. By now, there are few articles which research the control of multi-department as whole.This article researches the controlling strategies of multi-partment driving about the paper machine. This article introduces the whole structure and the running character of the paper machine, introduces the structure, running theory, the character of the figuration department and the compressing department of the paper machine, also introduces the key components of the paper machine. In this article the controlling theories connected with the multi-department driving is introduced briefly, controlling theory and the mathematic modal about the adaptive control based on MRAC are discussed particularly. Two methods of design the MRAC systems based on the Lyapunov stable theory and Popov stable theory are discussed in this article. Kinds of influenced tensional control is discussed such as illegible parameter PID adaptive control and adaptive tensional control, count out the mathematic model of the speed control using the local data. Using the two control strategies PID control and the adaptive control basing MRAC, the control result is tested by the Matlab computer emulator program. We find that comparative with tradition PID MRAC has strong ability of adaptive parameter change. The electric realizing method about the multi-department and the tensional control is discussed in this article.This article does some useful researching job about the development of Chinese equipment industry, and gives some result about the main factor of restraining this fields. If connected the controlling strategies introduced by this article and product area, I believe that it could promote the developing of Chinese equipment industry.
