Simulink Control Design™ - MathWorks

The software linearizes the portion of the model between the linearization input and

output at the default simulation time of 0, specified in Snapshot times parameter in

the Block Parameters dialog box, and plots the Bode magnitude and phase.

After the simulation completes, the plot window resembles the following figure.

The computed linear system is saved as sys in the MATLAB workspace. sys is a structure

with time and values fields. To view the structure, type:

sys

This command returns the following results:

sys =

time: 0

values: [1x1 ss]

blockName: 'watertank/Bode Plot'

• The time field contains the default simulation time at which the linear system is
  computed.
