Abstract: Projection to latent structures or partial least squares (PLS) is a multivariable statistical regression method based on projecting/viewing the information in a high-dimensional data space down onto a low dimensional one defined by some latent variables. PLS is successfully applied in diverse fields including process monitoring; identification of process dynamics & control and deals with noisy and highly correlated data, quite often, only with a limited number of observations available. The conventional PLS is suitable for modeling time independent or steady state processes. For modeling dynamic process, the input data matrix (X) is augmented either with large number of lagged input variables (called finite impulse response (FIR) model) or including lagged input and output variables (called auto regressive model with exogenous input, ARX). By combining the PLS with ARX and FIR model structure, non-linear dynamic processes can be modeled. In the present study, PLS algorithm was used...
