Identifying Linear Models

The following table summarizes the blocks you use to estimate model parameters in a Simulink model during simulation and export the results to the MATLAB environment.

After you add a block to the model, double-click the block to specify block parameters.

Block	Description
AR Estimator	Estimate AR model parameters from time-series data, which has one output and no input.
ARMAX Estimator	Estimate ARMAX model parameters from input/output data.
ARX Estimator	Estimate ARX model parameters from input/output data.
BJ Estimator	Estimate BJ model parameters from input/output data.
OE Estimator	Estimate OE model parameters from input/output data.
PEM Estimator	Estimate ARX, ARMAX, Box-Jenkins, and Output-Error models (idpoly objects) from single-input and single output data using general prediction-error method.

For information about configuring each block, see the corresponding reference pages.
