Trigger-Based Operating Point Snapshot

Generate operating points at triggered events

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.

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'
