Which control method employs feedback to adjust motor performance?

The closed-loop control method is characterized by its use of feedback to improve motor performance. In this system, sensors are employed to continuously monitor the output or actual performance of the motor. This real-time data is then compared to a desired setpoint or target value. If discrepancies arise between the actual performance and the setpoint, the system automatically makes adjustments to correct these deviations. This feedback mechanism allows for precise control over the motor, enhancing stability and responsiveness in various operating conditions.

In contrast, feedforward control provides adjustments based on anticipated changes rather than real-time feedback, which can lead to less accurate performance in dynamic situations. Open-loop control lacks any feedback mechanism altogether, relying solely on predetermined input settings, making it less adaptable. Manual control requires human intervention to adjust motor performance, which is not as efficient or responsive as a feedback-controlled system.
