Implementation of on-line control in chemical process plants
TL;DR: In all cases, the implementation of these aspects of modern control theory on a real process plant was successful, but pointed to several non-trivial complications which must be resolved before these algorithms can be adopted for general use in the process industries.

Identification and linear multivariable control in an absorption-desorption pilot plant
TL;DR: In this paper, a multivariable transfer function model was obtained from experimental input-output data in which the inputs (steam supply and liquid circulation rate) were perturbed simultaneously using uncorrelated pseudo random sequences.

On self tuning regulators
TL;DR: In this paper, the problem of controlling a system with constant but unknown parameters is considered and an algorithm obtained by combining a least squares estimator with a minimum variance regulator computed from the estimated model is analyzed.
Journal ArticleDOI
Design of multivariable control systems using the inverse Nyquist array
TL;DR: The inverse Nyquist array as discussed by the authors is a set of diagrams corresponding to the elements of the inverse of the open-loop transfer function of a control system, which can be used to investigate the stability of multivariable control systems.
Journal ArticleDOI
The design of linear multivariable systems
TL;DR: In this paper, a computer-aided procedure whereby a succession of single-loop designs, using Nyquist loci, yields a multivariable design which is stable and attenuates disturbances is described.
Journal ArticleDOI
Survey of applications of identification in chemical and physical processes
TL;DR: In this article, a survey of the application of system identification techniques to chemical, metallurgical, paper and pulp, cement and glass industries is presented, and the main conclusion is that interactive programs are very efficient for handling all the phases of model building due to its iterative nature.
Journal ArticleDOI
Multivariable parameter estimation using a 2-step least-squares estimator
TL;DR: In this article, a 2-step least-squares technique is extended to deal with the problem of estimating the parameters of the transfer function matrix of a multivariable linear discrete system.
