update - Update operating point object with structural changes in model

Syntax

update(op)

Graphical Alternative

As an alternative to the update function, update operating point objects using the Sync with Model button in the Simulink Control Design GUI. See Specifying Operating Points in the Simulink Control Design getting started documentation for more information.

Description

update(op) updates an operating point object, op, to reflect any changes in the associated Simulink model, such as states being added or removed.

Example

Open the magball model:

magball

Create an operating point object for the model:

op=operpoint('magball')

This syntax returns:

 Operating Point for the Model magball.
 (Time-Varying Components Evaluated at time t=0)

States: 
----------
(1.) magball/Controller/Controller
      x: 0            
(2.) magball/Magnetic Ball Plant/Current
      x: 7            
(3.) magball/Magnetic Ball Plant/dhdt
      x: 0            
(4.) magball/Magnetic Ball Plant/height
      x: 0.05         
 
Inputs: None

Add an Integrator block to the model, as shown in the following figure.

Update the operating point to include this new state:

update(op)

The new operating point appears:

 Operating Point for the Model magball.

(2.) magball/Magnetic Ball Plant/Current
      x: 7            
(3.) magball/Magnetic Ball Plant/dhdt
      x: 0            
(4.) magball/Magnetic Ball Plant/height
      x: 0.05         
(5.) magball/Integrator
      x: 0            
 
Inputs: None
