Control Structure Selection for an Evaporation Process

摘要

A systematic procedure for control structure selection is applied to the evaporation process of Newell and Lee (1989). First, promising sets of controlled variables are selected, based on steady-state economic criteria. The objective is to find sets of controlled variables which with constant setpoints keep the process close to the economic optimum ("self-optimizing control") in face of disturbances and implementation errors. Second, stabilization and controllability analysis is performed for the most promising sets of economic controlled variables.
