? Feedback control obtains data at the process output. Because of this, the control takes into
account unforeseen disturbances such as frictional and pressure losses.
- Feedback control architecture ensures the desired performance by altering the inputs
immediately once deviations are observed regardless of what caused the disturbance.
- By analysing the output of a system, unstable processes may be stabilized.
- Feedback controls do not require detailed knowledge of the system and, in particular, do
not require a mathematical model of the process.
- Feedback controls can be easily duplicated from one system to another. A feedback
control system consists of five basic components: (1) input, (2) process being controlled,
(3) output, (4) sensing elements, and (5) controller and actuating devices.
- A final importance of feedback control stems from the ability to track the process output
and, thus, track the system's overall performance.
