Servo System Closed-Loop Structure

A servo system closed-loop structure is a control method that achieves precise control of the system output by introducing a feedback loop. This structure comprises four main parts: a controller, actuators, sensors, and the controlled object. The controller generates control signals based on setpoints and current system state information fed back from the sensors; the actuators receive the control signals and control the controlled object; the sensors detect the state information of the controlled object and feed it back to the controller; the controlled object is the actual equipment or process that needs to be controlled. This closed-loop control method effectively improves system stability and accuracy and is widely used in various industrial control systems, robotic systems, etc.
