Revised January 1983] SUMMARY Stochastic approximation procedures are considered for the estimation of parameters using incomplete data. The conceptual model state is augmented by the vector of free parameters which are to be estimated from input-output data, and the extended Kaiman filter is used to recursively estimate and predict the augmented state. Recursive Identification and Parameter Estimation describes a recursive approach to solving system identification and parameter estimation problems arising from diverse areas. RECURSIVE PARAMETER ESTIMATION Recursive identification algorithm is an integral part of STC and play important role in tracking time-variant parameters. The method is capable of estimating impedance parameters of network branches in both online and offline modes. The recursive parameter estimation algorithms are based on the data analysis of the input and output signals from the process to be identified. The ex-periments include parameter estimation for a real-world pedestrian flow simulator (Yamashita et al., 2010), which may be of independent interest as application. This example shows how to perform online parameter estimation for line-fitting using recursive estimation algorithms at the MATLAB command line. Circuits Syst.

ISBN 978-80-7248-779-0. Tips Starting in R2016b, instead of using the step command to update model parameter estimates, you can call the System … The engine model is a damped second order system with input and output nonlinearities to account for different response times at different throttle positions. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We consider estimation procedures which are recursive in the sense that each successive estimator is obtained from the previous one by a simple adjustment. The output is estimated using input-output estimation data, current parameter values, and recursive estimation algorithm specified in obj. The software ensures P(t) is a positive-definite matrix by using a square-root algorithm to update it .The software computes P assuming that the residuals (difference between estimated and measured outputs) are white noise, and the variance of these residuals is 1.R 2 * P is the covariance matrix of the estimated parameters, and R 1 /R 2 is the covariance matrix of the parameter changes.
