Iddata Source
Import time-domain data stored in iddata
object in
MATLAB workspace
Libraries:
System Identification Toolbox
Description
The Iddata Source block imports the input-output time-domain data
stored in an iddata
object in the MATLAB® workspace. You can use this block to import data for simulating a model in
Simulink®.
Examples
Ports
Output
Input — Input data stored in iddata
object
scalar | vector
Input data stored in iddata
object, returned as a
scalar for single-input data and a vector of length
Nu for multichannel data with
Nu inputs. If z
is the
iddata
object, the output at this port at
simulation time t is z.InputData
at time t. If t is greater than
z.SamplingInstants(end)
, the maximum time in
z
, the input data is returned as
0
for each input channel.
Data Types: double
Output — Output data stored in iddata
object
scalar | vector
Output data stored in iddata
object, returned as a
scalar for single-output data and as a vector of length
Ny for multichannel data with
Ny outputs. If z
is the
iddata
object, the output at this port at
simulation time t is z.OutputData
at time t. If t is greater than
z.SamplingInstants(end)
, the maximum time in
z
, the output data is returned as
0
for each output channel.
Data Types: double
Parameters
IDDATA object — Time-domain data to be imported
iddata(1,1)
(default) | iddata
object
Time-domain data that is to be imported, specified as an
iddata
object that you have created in the
MATLAB workspace. The iddata
object must contain
only one experiment. For a multiple-experiment iddata
object z
, to specify an iddata
object
for experiment number kexp
, specify IDDATA
object as getexp(z,kexp)
.
