View and Modify Operating Point Object (MATLAB Code)

This example shows how to view and modify the states in a Simulink model using an operating point object.

Create an operating point object from the Simulink Model.

sys = 'watertank';
load_system(sys)
op = operpoint(sys)
 Operating point for the Model watertank.
 (Time-Varying Components Evaluated at time t=0)

States: 
----------
(1.) watertank/PID Controller/Integrator
      x: 0            
(2.) watertank/Water-Tank System/H
      x: 1            

Inputs: None 
----------

The operating point, op, contains the states and input levels of the model.

Set the value of the first state.

op.States(1).x = 1.26;

View the operating point state values.

op.States
(1.) watertank/PID Controller/Integrator
      x: 1.26         
(2.) watertank/Water-Tank System/H
      x: 1            

If you modify your Simulink model after creating an operating point object, then use update to update your operating point.
