looptune tunes the feedback loop illustrated
below to meet default requirements or requirements that you specify.
C represents the controller and
the plant. The sensor outputs
signals) and actuator outputs
signals) define the boundary between plant and controller.
The controller is the portion of your control system whose inputs
are measurements, and whose outputs are control signals. Conversely,
the plant is the remainder—the portion of your control system
that receives control signals as inputs, and produces measurements
For example, in the control system of the following illustration,
C receives the measurement
and the reference signal
r. The controller produces
qV as outputs.
C has a fixed internal structure.
a gain matrix
D , the PI controllers
and a summing junction. The
tunes free parameters of
C such as the gains in
the proportional and integral gains of
You can also use
looptune to co-tune free parameters
