Dynamic Regions Soft Partitioning and Its Application for Complex Process Systems

In this paper, the theories and methods of modeling of dynamic regions soft partitioning for complex process systems was researched. Every dynamic sub-region is one aggregation which including continuous variables and discrete events, and their mutual actions. At the same time, every dynamic sub-region is one unit, which has its dynamic characters and developing rules. Region overlapping, region floating and region zooming of the dynamic sub-region were studied, that region overlapping is the exterior character of the sub-region, region floating and region zooming are inner characters of the sub-region. Coke oven is a complex plant with the characters of large time-delay, strong non-linear, multivariable coupling and changeable parameters. The mean flue temperature is affected by many reasons; the dynamic process of the coke oven is driven by both continuous variables and discrete events. The process of coke oven was divided into several dynamic sub-regions according to dynamic regions soft partitioning method, which is the base to realize coke oven automatic control
