You can simulate the response of an identified model to given
inputs in the System Identification app
sim. You can predict
the model response a certain time horizon into the future using past
measurements of inputs and outputs. Use
predict model response over the time span of the measured data, and
forecast to predict the
response over a future time span when no measured data is available.
You can also import identified models to Simulink, and simulate
model response using model simulation blocks.
