Computing Operating Point Snapshots at Triggered

Events

This example shows how to generate operating points using triggered snapshots.

Generation of Operating Points Using Triggered Snapshots

Open the model.

In this example the model will be linearized at steady state operating points of 2500,

3000, and 3500 rpm. To get these operating points, simulation is used to generate

operating point snapshots of the steady state conditions. Since the exact time a system

reaches a steady state value is not always known, blocks such as the subsystem -

Generate settling time events can be built to generate settling events. The block in this

example sends rising edge trigger signals when a model is near a settling condition. The

mask shown below allows for multiple settling conditions to be entered. In this example

the block is configured to fire the rising edge triggers when the engine speed settles near

2500, 3000, and 3500 rpm for a minimum of 5 seconds.
