P Nordfeldt, T Hägglund - Journal of process control, 2006 - Elsevier
This paper treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a …
J Garrido, F Vázquez, F Morilla - Journal of process control, 2011 - Elsevier
This paper presents an extension of the inverted decoupling approach that allows for more flexibility in choosing the transfer functions of the decoupled apparent process. In addition …
Y Shen, WJ Cai, S Li - Control Engineering Practice, 2010 - Elsevier
A novel decoupling control system design for high-dimensional multi-input, multi-output (MIMO) processes is presented. Based on the Relative Normalized Gain Array (RNGA), an …
Q Xiong, WJ Cai, MJ He - Journal of process control, 2007 - Elsevier
In this paper, a novel engineering oriented control system design method for multivariable processes is presented. By employing the concepts of energy transmission ratio and …
J Garrido, F Vázquez, F Morilla - Journal of process control, 2012 - Elsevier
This paper presents a generalized formulation of simplified decoupling to n× n processes that allows for different configurations depending on the decoupler elements set to unity. To …
An analytical decoupling control method is proposed for multiple-input–multiple-output (MIMO) processes with multiple time delays. The desired diagonal system transfer matrix is …
In this article, a new analytical method based on the direct synthesis approach is proposed for the design of a multi-loop proportional-integral (PI) controller. The proposed design …
J Garrido, F Vázquez, F Morilla - Journal of Process Control, 2014 - Elsevier
This paper presents a new tuning methodology of the main controller of an internal model control structure for n× n stable multivariable processes with multiple time delays based on …
P Chen, W Zhang - ISA transactions, 2007 - Elsevier
This paper improves an inverted decoupling technique for a class of stable linear multivariable processes with multiple time delays and nonminimum-phase zeros. Two …
