Trigger-Based Operating Point Snapshot - Generate operating points, linearizations, or both at triggered events

Library

Simulink Control Design

Description

Attach this block to a signal in a model when you want to take a snapshot of the system's operating point at triggered events such as when the signal crosses zero or when the signal sends a function call. You can also perform a linearization at these events. To extract the operating point or perform the linearization, you need to simulate the model using either the findop or linearize functions or the simulation snapshots option in the Control and Estimation Tools Manager.

Choose the trigger type in the Block Parameters dialog box, as shown in the following figure.

The possible trigger types are

• rising: the signal crosses zero while increasing.

• falling: the signal crosses zero while decreasing.

• either: the signal crosses zero while either increasing or decreasing.

• function-call: the signal send a function call.

Note   The Simulink Control Design demo called "Trigger-Based Operating Point Snapshot" illustrates how to use this block.
