- Abstract
The problem of jointly designing the optimal steady-state transition and the related tracking controller for a representative class of exothermic continuous chemical reactors is addressed. The combination of optimal, constructive, and conventional control ideas yields a design methodology with: the identification of the underlying solvability conditions with physical meaning, the construction of the optimal transition, a controller to robustly perform the associated tracking task, and a closed-loop stability criterion coupled with conventional-like tuning guidelines. The controller is driven by a temperature measurement, simultaneously manipulates the heat exchange and reactant feed rates, and its implementation does not require the chemical kinetics model. The control scheme consists of a decentralized feedforward-feedback temperature loop and a ratio-type reactant dosage controller. The proposed transition and control design approach is illustrated with an application example treated with numerical simulations.
