Trigger-Based Operating Point Snapshot

R2026b

Generate operating points at triggered events

Trigger-Based Operating Point Snapshot block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Control Design / Utilities

Description

The Trigger-Based Operating Point Snapshot block takes snapshot operating points of a Simulink^® model at triggered events indicated by the input trigger signal. For example, you can configure the block to take a snapshot whenever the trigger signal crosses zero while increasing.

You can then linearize your model at the operating points using the linearize function or the Model Linearizer app.

Examples

Compute Operating Point Snapshots at Triggered Events

You can find an operating point by simulating the model until it is at steady state and taking a simulation snapshot.

Ports

Input

Trigger — Trigger control signal

scalar

Trigger control signal, specified as a scalar signal.

Parameters

Trigger type — Type of control signal

rising (default) | falling | either | function-call

Type of control signal that triggers the operating point snapshot.

• rising — Trigger when the control signal crosses zero while increasing.

• falling — Trigger when the control signal crosses zero while decreasing.

• either — Trigger when the control signal crosses zero while either increasing or decreasing.

• function-call: Trigger when the control signal receives a function-call event from a Stateflow^® chart, a Function-Call Generator block, an S-Function block, or a Hit Crossing block.

Programmatic Use

Block Parameter: 'TriggerType'

Type: character vector

Values: 'rising''falling''either''function-call'

Default: 'rising'

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"slctrl_utilities/Trigger-Based  Operating Point Snapshot"

Example: add_block("slctrl_utilities/Trigger-Based Operating Point Snapshot","myModel/myBlock",MakeNameUnique="on")

Version History

Introduced before R2006a

R2023b: Library location changed

The Trigger-Based Operating Point Snapshot block is now in the Simulink Control Design/Utilities sublibrary.

In R2023b, when you open a model saved in a previous release, the library links for Trigger-Based Operating Point Snapshot blocks update automatically.
