Update operating point object with structural changes in model

Syntax

update(op)

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.

Examples

Open the magball model:

magball

Create an operating point object for the model:

op = operpoint('magball')
 Operating Point for the Model magball.

(1.) magball/Controller/PID Controller/Filter
      x: 0            
(2.) magball/Controller/PID Controller/Integrator
      x: 14.0071           
(3.) magball/Magnetic Ball Plant/Current
      x: 7 .0036           
(4.) magball/Magnetic Ball Plant/dhdt
      x: 0            
(5.) 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)

View the updated operating point, which now contains a state for the integrator.

op
 Operating Point for the Model magball.
