What role does feedback play in a servo system?

In a servo system, feedback plays a critical role in ensuring accurate control of the output. The feedback mechanism involves continuously monitoring the output of the system, comparing it to the desired setpoint, and making adjustments as needed. This process allows the system to correct any deviations from the target performance, which is essential for precision applications found in robotics, automation, and various control systems.

By using feedback, the system can dynamically respond to changes in load conditions, mechanical tolerances, or external disturbances, maintaining the output at the desired levels. This mechanism is fundamental to achieving high accuracy and reliability in the operation of the servo system, thus reinforcing its importance in various engineering applications.
