(a) Figure 7.55 is a Simulink diagram for simulating the dynamic response of the nonlinear and
linearized system models.
The level H and temperature T of the nonlinear system are plotted in Figure 7.56. The transient
period is on the order of 300 min for level and 200 min for temperature.
(b) The linearized system outputs are shown in Figure 7.57.
(c) The nonlinear and linearized transient responses for level and temperature are compared in
Figure 7.58. For a 10% increase in inlet flow rate above
F
1
and a 10% decrease in inlet
temperature below
T
1
, the nonlinear system and linearized system approximation exhibit nearly
identical transient responses.
