System Identification Toolbox 7.3.1

Working with System Identification Toolbox

System Identification Toolbox facilitates the multistep process of identifying models from data. The toolbox enables you to:

• Analyze and process data
• Determine suitable model structure and order
• Estimate model parameters and validate model accuracy
• View the model responses and their uncertainties

You can perform these tasks by using either command-line functions or a graphical user interface (GUI).

You can convert the models into linear time-invariant (LTI) objects for use with Control System Toolbox. You can incorporate most identified models into Simulink models using blocks provided by the toolbox.
