Note the zero at the origin in. Because of this zero, we cannot achieve zero steady-
state error and must instead focus on the transient response to acceleration commands.
Note that acceleration commands are transient in nature so steady-state behavior is not a
concern. This zero at the origin also precludes pure integral action so we use a pseudo-
integrator with = 0.001.
Tuning Setup
When the control system is modeled in Simulink, you can use the slTuner interface to
quickly set up the tuning task. Open the Simulink model of the autopilot.
