Simulink Control Design™ - MathWorks

(Tuis.) #1

Within the Linear Analysis Tool, you cannot edit the values of the model initial condition
operating point or the values of an operating point that you found using trimming.


To edit an operating point that you found using a simulation snapshot, in the Edit dialog
box, in the Value column, select the state or input you want to edit, and enter the new
value. If your simulation snapshot was at a steady state, changing any values in the
Linear Analysis Tool can place the operating point into a non-steady-state condition.


View and Modify Operating Point at the Command Line


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';
open_system(sys)
op = operpoint(sys)


Operating point for the Model watertank.
