Dynamic Matrix Control Multivariable Controllers

Abstract

During the last 10 years, the use of model-based control in industry has increased dramatically. Distillation towers are prime targets for such controllers because of their long dynamics, multivariable nature, and requirement for tight composition control (motivated by efforts to improve product quality through decreased variation). In addition, distillation towers are commonly the unit or plant constraint to higher production. This is due primarily to the high cost of debottlenecking or replacing distillation towers.
