Keywords: control assessment, screening control alternatives, control decoupling


This work describes a methodology for the assessment of control alternatives of a given process. With this methodology once the process model is developed, it is linearized to evaluate different control criteria aiming to discern between viable combinations of measurements and controls. To cover the different alternatives of control pairs, all the possible alternatives are generated; then, for a rapid reduction of the number of candidates, the most strict control criteria are applied first. Later, less strict control criteria are applied sequentially to the remaining candidates. The most promising candidates are used to synthesize a decoupled control obtained as a precompensator optimized for diagonal dominance. This methodology is implemented using a pattern-based paradigm, which is applied to the analysis of a separation by a double effect evaporator and two distillation process with different degrees of detail.
