sdo.SystemLoggingInfo

Specify linear system logging information

Description

Specify linear system logging information. Use sdo.SystemLoggingInfo object to set the SystemLoggingInfo property of sdo.SimulationTest, to specify linear systems to log when simulating the model. You can configure sdo.SystemLoggingInfo to compute the linear system with or without using any frequency-domain check blocks defined in the model.

Creation

Syntax

sys = sdo.SystemLoggingInfo

sys = sdo.SystemLoggingInfo(PropertyName=Value)

Description

sys = sdo.SystemLoggingInfo constructs an sdo.SystemLoggingInfo object, sys, with default linear system logging settings. To modify settings for your specific application, use dot notation.

sys = sdo.SystemLoggingInfo(PropertyName=Value) specifies additional linear system logging settings, using name-value arguments.

Output Arguments

sys — Linear system logging information

sdo.SystemLoggingInfo object

Linear system logging information, returned as an sdo.SystemLoggingInfo object.

Properties

Source — Specify how to compute the linear system

'' (default) | character vector

Specify how to compute the linear system, with or without using frequency-domain check blocks in the model, specified as a character vector. To use a frequency-domain check block in the model, specify Source as the full path of the check block. For example, 'sdorectifier/Filter Design Requirements'. To not use a model check block, set Source to a name or use the default value ''.

LoggingName — Name used for the computed linear system

'sys' (default) | character vector

Name used for the computed linear system, specified as a character vector. LoggingName appears in the sdo.SimulationTest.LoggedData when the simulation is run.

LinearizationIOs — Linearization input/output points

[] (default) | vector of linearization IOs

Linearization input/output (IO) points, specified as a vector of linearization IOs. Create LinearizationIOs using the linio (Simulink Control Design) command from Simulink^® Control Design™.

If Source is specified as path to a model frequency-domain check block, and LinearizationIOs is non-empty, the linearization IO points of the check block are overwritten when the model is simulated.

SnapshotTimes — Linearization snapshot times

[] (default) | scalar | vector of scalars

Linearization snapshot times, specified as a scalar or vector of scalars.

If Source is specified as path to a model frequency-domain check block, and SnapshotTimes is non-empty, the linearization snapshot times of the check block are overwritten when the model is simulated.

LinearizationOptions — Linearization options

[] (default) | linearization option set

Linearization options to use when computing the linear system, specified as a linearization option set. To set these options, use the linearizeOptions (Simulink Control Design) command from Simulink Control Design.

If Source is specified as path to a model frequency-domain check block, and LinearizationOptions is non-empty, the linearization options of the check block are overwritten when the model is simulated.

Examples

Specify Linear System Logging Settings

Open the model.

open_system('sldo_model1')

Specify the input and output points that define the linear system to be computed.

IOs(1) = linio('sldo_model1/Sum',1,'input');
IOs(2) = linio('sldo_model1/Plant',1,'output');

Create an sdo.SystemLoggingInfo object to specify the linear system logging settings.

sys1 = sdo.SystemLoggingInfo;
sys1.Source = 'Specified IOs';
sys1.LoggingName = 'Linear_System';
sys1.LinearizationIOs = IOs;
sys1.SnapshotTimes = 0;
