Structure of Control System for Tuning With looptune
looptune tunes the feedback loop illustrated
below to meet default requirements or requirements that you specify.
C represents the controller and
G represents 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 as outputs.
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
