System Identification Toolbox

Examining Models

Having estimated a model is just a first step. It must now be examined, compared with other models, and tested with new data sets. This is primarily done using the six Model View functions, at the bottom of the main ident window:

• Frequency response
• Transient response
• Zeros and poles
• Noise spectrum
• Model output
• Model residuals

In addition, you can double-click on the model's icon to get Text Information about the model. Finally, you can export the model to the MATLAB workspace and use any commands for further analysis and model use.
