文摘

The objectives of this part of the two part paper are (i) development of signed digraph (SDG)models for control loops and (ii) discussion of a framework for application of graph-basedapproaches at a flowsheet level. Further, two case studies are used to explain the methodsdeveloped in part 1¹ (Ind. Eng. Chem. Res. 2003, 42, in press) and this paper. The first casestudy (continuous stirred tank reactor case study) explains the basic concepts of the generateand test method for SDG analysis, generation of redundant equations using algebraic manipulation, and analysis of systems with a single control loop. Case study 2 (flash vaporizer case study)deals with different methods of generating redundant equations and the analysis of systemswith multiple interacting control loops.
