Multivariable Constrained Generalized Predictive Control Strategy for the FCCU Main Fractionator

The FCCU main fractionator dynamic model is built. Based on this model the multivariable constrained generalized predictive control strategy is carried out to maintain the product quality at desirable specifications. The cascade control structure is adopted to ensure the operation security. Finally, the closed loop control simulation shows it is effective, which gives a promising introduction to its future on line implementation.
