Closed-loop controller

A closed-loop controller is a type of control system that uses feedback to adjust its output based on the difference between a desired setpoint and the actual output. This feedback mechanism allows the system to automatically correct any deviations from the desired performance or target values. ### Key Features of Closed-Loop Controllers: 1. **Feedback**: They continuously monitor the output of the system and feed this information back to the controller. This is essential for the system to make real-time adjustments.
