11 Using System Identification Toolbox™ Blocks
System Identification Toolbox Block Library
System Identi fication Toolbox provides blocks for sharing information
between the MATLAB and Simulink environments.
You can use the System Identification Toolbox block library to perform the
following tasks:
• Stream time-domain data source (
iddata object) into a Simulink model.
• Export data from a s imulation in Simulink software as a System
Identification Toolbo x data object (
iddata object).
• Import estimated m odels into a Simulink model and simulate the models
with or without noise.
The m odel you import might be a component of a larger system modeled in
Simulink. For example, if you identi fied a plant model using the System
Identification Toolbox software, you can import this plant into a Simulink
model for control design.
• Estimate parameters of linear polynomial models during simulation from
single-output data.
