A servo control system is a feedback control system that is used to accurately follow or reproduce a process. In many cases, the servo system specifically refers to the feedback control system in which the controlled quantity (the output of the system) is the mechanical displacement or displacement velocity and acceleration, and its function is to make the output mechanical displacement (or rotation angle) accurately track the input displacement (or rotation angle).
The structural composition of the servo system is not in principle different from other forms of feedback control systems.
The structure of the mechatronics servo control system has many types, but from the perspective of automatic control theory, the servo control system generally includes five parts: controller, controlled object, execution link, detection link, and comparison link.
1. Comparison link: The comparison link is to compare the input command signal with the feedback signal of the system to obtain the deviation signal between the output and the input, which is usually realized by a special circuit or computer.
2. Controller: The controller is usually a computer or PID control circuit, and its main task is to transform the deviation signal output by the comparison element to control the actuator to act according to the requirements.
3. Execution link: The function of the execution link is to convert the input various forms of energy into mechanical energy according to the requirements of the control signal to drive the controlled object to work. The actuators in the mechatronics system generally refer to various motors or hydraulic, pneumatic servo mechanisms, etc.
4. Controlled object: mechanical parameters including displacement, velocity, acceleration, force, and torque are controlled objects.
5. Detection link: The detection link refers to the device that can measure the output and convert it into the dimension required for the comparison link, which generally includes a sensor and a conversion circuit.
Servo control systems were originally used in ship autopilot, artillery control, and command instruments, and later gradually spread to many fields, especially automatic lathes, antenna position control, missile and spacecraft guidance, etc.

Estun servo motor - how to choose a servo motor?
The selection of servo motor is not only affected by the weight of the mechanism, but also the movement conditions of the equipment will also change the selection of servo motor. The greater the inertia, the greater the acceleration and deceleration torque, and the shorter the acceleration and deceleration time, the greater the output torque of the servo motor. When choosing a servo motor specification, follow the steps below.
