| Abstract: | Controllability should be considered at the design stage before control system is designed, as it is an inherent property of process. Structural information makes controllability assessment possible by giving insights on the pathways of disturbances in the process. In this study, a simple procedure to evaluate controllability is suggested to select design alternatives. This procedure is useful in screening out the design alternatives before using detailed controllability evaluation methods such as dynamic simulation. |
