Simulation and Prediction

Simulate or predict response of identified models; import identified models in Simulink® using model simulation blocks

You can simulate the response of an identified model to given inputs in the System Identification app and using sim. You can predict the model response a certain time horizon into the future using past measurements of inputs and outputs. Use predict to predict model response over the time span of the measured data, and use 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.
