To improve the precision of servo motor control,you can consider the following aspects:

Closed-loop Control:
Install encoders or sensors on the output shaft of the servo motor for real-time feedback and

control. This allows accurate capture and adjustment of motor speed, rotation angle, and

position, achieving high-precision control.

Optimize Dynamic Response:
Although servo motors have fast dynamic response and high acceleration, optimizing their

dynamic response can further improve precision. This can be achieved by adjusting motor

parameters and optimizing control algorithms.

Reduce Inertia:
Servo motors often use lightweight materials and structural designs to reduce rotor inertia.

This can improve the motor's response speed and control precision, enabling more precise motion control.

Adopt Magnetic Bearing Technology:
Magnetic bearing technology can reduce friction and mechanical wear in servo motors,

improving motion precision and reliability.

Optimize Temperature Control:
Temperature control has a significant impact on the motion precision of servo motors. By

using high-precision temperature sensors to monitor and control the internal temperature of

the motor, it can be maintained within the optimal operating temperature range, improving

motion precision and stability.

Optimize Control System:
Selecting a high-performance control system, such as a controller with adaptive PID control

algorithms, can help address issues like unstable dynamic response. Adjusting the PID

parameters of the servo motor can also improve its control precision.

Reduce Mechanical Transmission Error:

Mechanical transmission error is an important factor affecting the control precision of servo

motors. Therefore, methods such as increasing the gear size of the reducer, designing a

reasonable transmission structure, and optimizing the selection and combination of

transmission chains can effectively reduce mechanical transmission error and improve control

precision.

Purchase Quality Equipment:

Selecting quality servo motor equipment is crucial. Poor-quality products may have issues like

process deviations and structural problems, which can greatly hinder subsequent control and

precision improvement.
