getlinio
Obtain linear analysis points from Simulink model, Linear Analysis Plots block, or Model Verification block
Description
Examples
Obtain Analysis Points from Simulink Model
Open Simulink model.
mdl = 'scdpwm';
open_system(mdl)
This model contains the following linear analysis points:
Input perturbation at the output of the Step block
Output measurement at the output of the Plant Model block
Obtain the analysis points from the model.
io = getlinio(mdl)
2x1 vector of Linearization IOs: -------------------------- 1. Linearization input perturbation located at the following signal: - Block: scdpwm/Step - Port: 1 2. Linearization output measurement located at the following signal: - Block: scdpwm/Plant Model - Port: 1
You can use these analysis points for subsequent linearizations of the model using the linearize
command or an slLinearizer
interface.
Obtain Analysis Points from Linear Analysis Plots Block
Open Simulink model.
open_system('scdcstr')
This model contains a Bode Plot block that is configured with the following linear analysis points:
Input perturbation at the output of the Coolant Temp block
Output measurement at the
CA
output of the CSTR block
Obtain the analysis points from the Bode Plot block.
io = getlinio('scdcstr/Bode Plot')
2x1 vector of Linearization IOs: -------------------------- 1. Linearization input perturbation located at the following signal: - Block: scdcstr/Coolant Temp - Port: 1 2. Linearization output measurement located at the following signal: - Block: scdcstr/CSTR - Port: 2
Input Arguments
mdl
— Simulink model name
character vector | string
Simulink model name, specified as a character vector or string. The model must be in the current working folder or on the MATLAB® path.
If the model is not open or loaded into memory, getlinio
loads
the model into memory.
blockpath
— Linear Analysis Plots block or Model Verification block
character vector | string
Linear Analysis Plots block or Model Verification block, specified as a character vector or string that contains its full block path. The model that contains the block must be in the current working folder or on the MATLAB path.
For more information on:
Linear analysis plot blocks, see Visualization During Simulation.
Model verification blocks, see Model Verification.
Output Arguments
io
— Analysis point set
linearization I/O object | vector of linearization I/O objects
Analysis point set, returned as a linearization I/O object or
a vector of linearization I/O objects. Use io
to
specify linearization inputs, outputs, and loop openings when using
the linearize
command. For
more information, see Specify Portion of Model to Linearize.
Each analysis point has the following properties:
Property | Description |
---|---|
Active | Flag indicating whether to use the analysis point for linearization, specified as one of the following:
|
Block | Full block path of the block with which the analysis point is associated, specified as a character vector. |
PortNumber | Output port with which the analysis point is associated, specified as an integer. |
Type | Analysis point type, specified as one of the following:
For more information on analysis point types, see Specify Portion of Model to Linearize. |
BusElement | Bus element name with which the analysis point is associated,
specified as a character vector or |
Description | User-specified description of the analysis point, which you can set for convenience, specified as a character vector. |
