Identifying Linear Models
Identifying L inear Models
The follow ing table summarizes the blocks you use to estimate model
parameters in a Simulink model during simulation and export the results to
the M ATLAB environment.
After you a dd a block to the m odel, double-click the block to specify block
parameters.
Block
Description
AR Estimator Estimate A R 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 p aram eters from
input/output data.
BJ Estimator
Estimate BJ model parameters from input/output
data.
OE Estim ator 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.
