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
