in which Au is a vector with the changes in process inputs, A is a matrix with step weight coefficients which represent the model dynamics, T is a diagonal matrix with weights representing the relative importance of the process outputs, Tm is a diagonal matrix with penalties for the process input changes and e is a vector of process output error predictions into the future.

Model predictive control works well for distillation columns; it becomes more attractive for larger systems, such as heat-integrated distillation columns.

One of the major benefits of model predictive control is its capability in handling constraints. In that case the control problem is usually solved using quadratic programming or some other optimization technique. Commercial software packages are available for model identification and controller implementation.
