The Study Of Application About Advanced Control And Communication Technology In DCS

In recent years DCS has been introducing into industry controlsystem in china widely, and an environment has provided for theapplication of advanced control strategies. Because of the complecities,safety and reliability of thermal processes, the application of advancedcontrol technology in thermal processes is limited.It makes slowprogress.This text regards DCS as the research center,studys the adaptivepredictive control and something about PROFIBUS.During the study ofadvanced control arithmetic theory and the practically apply ofcommunication technology, the article has always been closely combined with the actual situation of china’s power plant control, takethe control matter of thermal processes as a starting point, seize thecharacteristics of large time delay system, does a point of exploringwork to solve the problem of large time delay control, according to theDCS.The main research can be summarized as follows:1. Analyse the smith predictor compensation and adaptive controlalgorithm. The results of simulation show the defects of the conventionalsmith arithmetic in the large time delay process control.So,it advancesthe next step to explore. We do some theoretical analysis about smithmodel reference adaptive algorithm, and do some simulation. Andcompared with the conventional method of compensation, reflecting thesuperiority of advanced algorithms.2. Do some simulation study about smith predictor, model referenceadaptive algorithm and smith-fuzzy arithmetic.3. Do some exploring about ways to apply in DCS about control arithmetic, especially for advanced control strategies.4. Introduce the FIELDBUS briefly, and, according to examples tointroduce the application of PROFIBUS in DCS.The papers can be generally divided into two parts:The first part is about advanced algorithms applications inDCS,including advanced algorithms theoretical analysis,simulation,andits realization in DCS.The second part is about the apply in DCS aboutPROFIBUS.And this part is mainly rely on examples to introduce it indetail.
