The major work on rational model identification is summarised in the following categories: linear least squares (LLS) algorithms for parameter estimation—extended LLS estimator, recursive LLS estimator, orthogonal LLS structure detector and estimator, fast orthogonal algorithm, and implicit least squares algorithm, and nonlinear least.

In this study, an enhanced Kalman Filter formulation for linear in the parameters models with inherent correlated errors is proposed to build up a new framework for nonlinear rational model parameter estimation. The mechanism of linear Kalman filter (LKF) with point data processing is adopted to develop a new recursive algorithm.

As an alternative, for nonlinear discrete-time models with a so-called rational structure in input, output, and parameters, in this paper a method is proposed to re-parameterize the model such.

This book determines adjustable parameters in mathematical models that describe steady state or dynamic systems, presenting the most important optimization methods used for parameter estimation.

It focuses on the Gauss-Newton method and its modifications for systems and processes represented by algebraic or differential equation models. We present an algorithm for recursive estimation of parameters in a mildly nonlinear model involving incomplete data.

In particular, we focus on the time-varying deterministic parameters of additive noise in the nonlinear model. For the nonstationary noise that we encounter in robust speech recognition, different observation data segments correspond to different noise parameter.
