Using Models with Control System Toolbox™ Software
model = model('measured')
% Convert to LTI object
LTI_sys = idss(model)
The LTI object includes only the dynamic model and not the noise model,
which is estim a t ed f or every linear m od el in the System Iden tification Toolbox
software.
Note To include noise channels in the LTI models, first use noisecnv to
convert the noise in the
idmodel object to measured channels, and then
convert to an LTI object.
For more information about subreferencing the dynamic or the noise model,
see “Subreferencing Measured and Noise Models” on page 3-120.
Viewing Model Response Using the LTI Viewer
• “What Is the LTI Viewer?” on page 10-5
• “Dis playing Identified Models in the LTI View er” on page 10-6
What Is the LTI Viewer?
If you have the Control System Toolbox software, you can plot models in the
LTI Viewer from either the Sy stem Identification Tool GU I or the MATLAB
Command Window.
The LTI Viewer is a g raphical user interface for viewing and manipulating
theresponseplotsoflinearmodels.
Note The LTI Viewer does not display model uncertainty.
For more information about working with plots in the LTI Viewer, see the
Control System Toolbox documentation.
