【 摘 要 】

References(14)Cited-By(5)The perturbed linear system equations for a binary distillation column with pressure variation are derived. The application of modern control theory to this model shows that there exists a pair of constant precompensator and state variable feedback which completely decouples the system and rejects the effect of the feed composition disturbance. Based on the subspace concept, we found that five state variables have to be measured and three poles can be arbitrarily assigned. If we use the dynamic precompensator, seven poles can be assigned while eight measurement variables are required. A simulation study was carried out to show the power of the approach.
