What type of control system utilizes feedback to adjust its operation?

A closed-loop control system incorporates feedback to adjust its operation, which allows for more precise control over a process. In this system, the output is monitored, and that information is sent back to the controller. The controller then processes this feedback to make necessary adjustments to the input or operational parameters, effectively correcting any deviations from a desired set point.

This self-regulating feature enables closed-loop systems to maintain stability and improve accuracy by continuously comparing the actual output to the desired output and making appropriate changes. This characteristic distinguishes closed-loop systems from others, as open-loop systems do not rely on feedback and are therefore unable to adapt to changes in operating conditions. Similarly, feedforward control systems predict and compensate for disturbances before they affect the output but do not utilize feedback. Manual control systems require human intervention to make adjustments rather than relying on automatic feedback processes.
