Simulate Simulink Model at Specific Operating Point

This example shows how to initialize a model at a specific operating point for simulation.

For more information on computing operating points, see “Compute Steady-State

Operating Points” on page 1-6 and “Find Operating Points at Simulation Snapshots” on

page 1-108

To simulate your model at your computed operating point, you must set the model initial

conditions to match the states and inputs in the operating point.

If you already have an operating point, op, in your MATLAB or model workspace, you can

set the initial conditions in the Configuration Parameters dialog box, in the Data Import/

Export pane. To do so:

• Set the Input parameter to getinputstruct(op).


• Set the Initial state parameter to getstatestruct(op).

Alternatively, if you computed your operating point using the Steady State Manager or

Linear Analysis Tool, you can interactively set the model initial conditions form within

these tools.

Once you have set your model initial condition, simulate your model at the specified

operating point. In the Simulink Editor, select Simulation > Run.

Set Model Operating Point Using Steady State Manager

In the Steady State Manager, in the Data Browser, in the Operating Point section,

right-click the operating point at which you want to simulate the model, and select Open

Selection.

If you computed multiple operating points using a simulation snapshot, in the operating

point document, select an operating point from the Select Operating Point drop-down

list.
