Study Notes

Open-loop Systems

Operates without feedback
Directly generates output in response to an input signal

Closed-loop Systems (Feedback Control Systems)

Maintain a prescribed relationship between system variables
Uses the difference between desired and actual outputs to control system behavior

Properties of Closed-loop Systems

Good regulation against disturbances
A component or process to be controlled can be represented graphically
The input-output relationship represents the cause-and-effect relationship of the process
The process transforms the input signal into a desired output signal
