Simulink® Control Design™

Extracting Values from Simulation

This section continues the example from Example: Water-Tank System. At this stage in the example, linearization point objects have been created in the MATLAB^® workspace. See Configuring the Model for Linearization Using Functions for more information on creating linearization point objects.

Use Simulink^® Control Design™ software to extract operating points from a simulation of your model at specified times, such as when the simulation reaches a steady state solution.

For example, to create an operating point object for the water-tank model after it has simulated for 20 time units, type

watertank_op=findop('watertank',20)

MATLAB software displays the operating point at time t=20.
