  4. Abstract:
  5. Application of advanced process control methods in a chemical plant requires a model which represents the transient behaviour of the plant. However, only a few plant-wide identification methods have been proposed for chemical processes. In this paper, an objectoriented process identifier (OPI) framework has been introduced for plant-wide identification to show how using object-oriented design can provide a general plant-wide modelling framework for various systems including chemical processes. The interactions between units are considered in plant-wide identification methods. As a result, the obtained models can predict the system behaviour in new operating conditions better than those obtained from the separate identification of units in the plant. The performance of the OPI has been evaluated through its application for identification of two benchmark case studies which are frequently used by the research community of nonlinear process control. According to the results obtained from these case studies, OPI is flexible and robust enough to capture the dynamic behaviour of the system using a minimum amount of information
