What type of control system adjusts its operations based on input from sensors?

A closed loop control system is characterized by its ability to adjust its operations based on feedback received from sensors. In this type of system, sensors continuously monitor the output or process variable and relay information back to the controller. The controller then compares this feedback to a desired setpoint and makes adjustments to the process as necessary to ensure that the output remains as close to the setpoint as possible.

This feedback mechanism allows for greater accuracy and stability in maintaining the desired operational parameters since any deviations can be corrected in real-time. In contrast, the other types of control systems do not incorporate this feedback loop to modify their operation dynamically in response to changes in the output. Open loop control systems operate without feedback, manual control relies on human intervention, and feedback control can be related to closed loop systems but generally refers to the method of using feedback to manage control.
