“…Liu 23 develops an analytical decoupling control on the basis of the H 2 optimal performance specifications. Other methodologies 17,21,22 reduce the K(s) elements to PID controllers obtaining as result a multivariable PID control. This reduction is performed because PID controllers are preferred over more advanced controllers in many practical applications (unless PID controls cannot meet the specifications).…”

Abstract:This paper presents a new methodology of multivariable centralized control based on the structure of inverted decoupling. The method is presented for general n×n processes, obtaining very simple general expressions for the controller elements with a complexity independent of the system size. The possible configurations and realizability conditions are stated. Then, the specification of performance requirements is carried out from simple open loop transfer functions for three common cases. As a particular case, it is shown that the resulting controller elements have PI structure or filtered derivative action plus a time delay when the process elements are given by first order plus time delay systems. Comparisons with other works demonstrate the effectiveness of this methodology through the use of several simulation examples and an experimental lab process.

“…On the other hand, Figure 1b represents a pure centralized control system with K(s) being the n-dimensional full matrix controller. Under the paradigm of decoupling control, some methodologies [17][18][19][20][21][22][23][24] have been developed using this scheme. Most of them propose to find a K(s)…”
