Noise handling capabilities of multivariate methods
(Journal article; Peer reviewed, 2002)The noise handling capabilities of principal component regression (PCR) and partial least squares regression (PLSR) are somewhat disputed issues, especially regarding regressor noise. In an attempt to indicate an answer ... -
On primary output estimation by use of secondary measurements as inputsignals in system identification
(Journal article; Peer reviewed, 1999)In many cases, vital output variables in, e.g., industrial processes cannot be measured online. It is then of interest to estimate these primary variables from manipulated and measured inputs and the secondary output ... -
On Tuning PI Controllers for Integrating Plus Time Delay Systems
(Journal article, 2010)Some analytical results concerning PI controller tuning based on integrator plus time delay models are worked out and presented. A method for obtaining PI controller parameters, Kp = k , and, Ti = , which ensures a ... -
PCR/PLSR optimization based on noise covariance estimation and Kalman filtering theory
(Journal article; Peer reviewed, 2002)The theoretical connection between principal component regression (PCR) and partial least squares regression (PLSR) on one hand and Kalman filtering (KF) on the other is known from earlier work. In the present paper we ... -
PLS post-processing by similarity transformation: a simple alternative to OPLS
(Journal article; Peer reviewed, 2005)Several methods for orthogonal signal correction (OSC) based on pre-processing of the modeling data have been developed in recent years, and OPLS (orthogonal projections to latent structures) is a well known algorithm. ... -
PLS score-loading correspondence and a bi-orthogonal factorization
(Journal article; Peer reviewed, 2002)It is established industrial practice to use the correspondence between partial least squares (PLS) scores and loadings or loading weights as a means for process monitoring and control. Deviations from the normal operating ... -
Re-interpretation of NIPALS results solves PLSR inconsistency problem
(Journal article; Peer reviewed, 2009)The well-known nonlinear iterative partial least squares (NIPALS) algorithm is commonly used for computation of components in partial least squares regression (PLSR) with orthogonalized score vectors. Based on generalized ... -
Reduced PCR/PLSR models by subspace projections
(Journal article; Peer reviewed, 2006)Latent variables models used in principal component regression (PCR) or partial least squares regression (PLSR) often use a high number of components, and this makes interpretation of score and loading plots difficult. ... -

The Good Gain method for simple experimental tuning of PI controllers
(Journal article; Peer reviewed, 2012)A novel experimental method { here denoted the Good Gain method { for tuning PI controllers is proposed. The method can be regarded as an alternative to the famous Ziegler-Nichols' Ultimate Gain method. The approach taken ...
