This paper describes an Interactive Tool for Control Relevant Identification (ITCRI). It evaluates all stages of a control-relevant identification process, from input design to closed-loop control, simultaneously and interactively in one screen. Control-relevance in ITCRI is accomplished primarily through prefiltering, which is implemented via single-pass and two-step algorithms. By simultaneously displaying both open- and closed-loop responses of the estimated models and important control-relevant validation criteria, ITCRI enables the user to readily assess how design variable choices and control performance requirements impact model error and ultimately, closed-loop performance. A case study involving a fluidized bed calciner is presented to illustrate the workings of the tool and the considerations that arise when control requirements are incorporated during identification.
