强调混杂系统的分析,研究了一类化工过程控制系统的混杂系统特性,建立了由过程层、监控层和调度层组成的混杂系统多层混合模型结构。论文分别讨论了各层混杂系统的模型形式,特别对过程控制层混杂系统模型进行了详细的描述。引入Petri网作为描述化工过程控制混杂系统的方法,以化工溶剂回收过程为例,建立了基于混合Petri网的过程控制层的模型。论文的工作为深入研究化工过程控制混杂系统奠定了基础。
The analysis of hybrid system is emphasized. The hybrid system characteristics of a kind of chemical process control system are studied. The hybrid multi-layer model structure of hybrid system is established, which consists of process layer, monitoring layer and scheduling layer. The dissertation discusses the model forms of the hybrid systems at all levels and the hybrid system models of the process control layer in detail. Petri net is introduced as a method to describe chemical process control hybrid system. Taking chemical solvent recovery process as an example, a model of process control layer based on hybrid Petri net is established. Papers work for the further study of chemical process control hybrid system laid the foundation.
