Figure 1: Multivariable control matrix for an atmospheric crude distillation column, based on operation-driven design practice. The matrix is smaller than traditional crude column applications. It addresses primarily column pressure and product inferential quality control, which are often the most valuable objectives of this application – and often the ones found “unclamped” in existing large-matrix applications.

Operation-driven matrix design

A multivariable control matrix has manipulated variables (MVs) on one axis, controlled variables (CVs) on the other axis, and models in the matrix that indicate a relationship between that MV/CV pair. Effective multivariable controllers use the right models for various control and optimization needs.
