Control system design involves input/output (IO) selection, that is, decisions on the number,
the place, and the type of actuators and sensors. The choice of inputs and outputs affects the …

This work presents a comprehensive classification of the different methods and procedures
for integrated synthesis, design and control of chemical processes, based on a wide revision …

Control structure (strategy) selection consists of the selection and pairing of manipulated
and measured variables. This article outlines a procedure that uses such tools as the …

Controllability is one of the most important aspects of chemical process operability, because
it can be used to assess the attainable operation of a given process and improve its dynamic …

In this study, a two-level control methodology consisting of an upper-level scheduler and a
lower-level supervisory controller is proposed for an advanced load-following energy plant …

Two open-loop analysis techniques for assessing input-output controllability in the presence
of control constraints are presented. The techniques used are a modified singular value …

A procedure for analyzing the input-output controllability of single-input single-output (SISO)
systems is presented. This procedure is applied to a pH neutralization process which must …

Multivariable 5× 5 distillation control, ie. control of levels, pressure and compositions by one
multivariable controller, provides opportunities to improve the control performance as …

The concept of plantwide control structure synthesis is not new to the chemical process
industry. The approaches used can be classified into two main categories: a process …

The purpose of this paper is to introduce the reader to multivariable frequency domain
methods including H∞-design. These methods provide a direct generalization of the …
