Research And Implementation Of Distributed Process Wind Control System Based On Fieldbus

In recent years, the fieldbus technology and process control technology has beenrapid development. Advanced process control technology based on the industrial fieldbus has been widely used in tobacco industry. The stability of the supply pressure,pressure control precision, the rapidity of system response is very important in thefeeding process in the Cigarette production. Research of this paper is committed toimprove the fault tolerance and reliability of existing process wind system, enhancethe volume after the machine pressure supply control accuracy and stability.First, this paper studied the PROFIBUS and PROFINET fieldbus networktopology structure, the transmission medium, network connection and diagnosis, etc.On process of wind power system and process and control process are studied. Factorsinfluencing the stability of the system are summarized. Then studied the automaticcontrol field in recent years more popular control law, Combining with the newrequirements of process wind power supply, is presented based on the industrial fieldbus control functions dispersed distributed control system.In this paper, we design the wind distributed process control system. From twoaspects of hardware and software, we completed the construction of the system andthe communication function. And emphatically aiming at random key unit volume, isput forward to the method of fuzzy PID control to adjust the frequency output to adaptto the change of the load. Completed a master station and substation respectivelycontrol program design and parameter setting.Finally, through the data at the scene debugging machine phase randomlycollected data analysis found that the system response is rapid, stable pressure, caneffectively achieve control requirements. In the volume of joint process has practicalvalue and popularization meaning wind control field.
