Description

technical field [0001] The invention relates to a servo motor control system suitable for an optical fiber winding machine, belonging to the technical field of optical fiber gyro. Background technique [0002] The fiber optic gyroscope is mainly used to measure the spatial motion attitude of the sensitive carrier, which plays a key role in the performance of the navigation system; the fiber optic ring is the core component of the fiber optic gyroscope, the winding method of the fiber The tension on the fiber is the main factor affecting the performance of the fiber optic gyroscope. During the fiber winding process, the servo motors of each axis will start and stop frequently and perform multi-axis coordinated control; if the start and stop control of the servo motors are not properly controlled, there will be start-up vibration and stop overshoot; The speed is slow and the control accuracy is low, which not only affects the tension control accuracy of the optical fiber when...

AI Technical Summary

Problems solved by technology

During the fiber winding process, the servo motors of each axis will start and stop frequently and perform multi-axis coordinated control; if the start and stop control of the servo motors are not properly controlled, there will be start-up vibration and stop overshoot; The speed is slow and the control accuracy is low, which not only affects the tension control accuracy when the fiber is looped, but also causes the fiber to fall off or break when it is serious, resulting in the failure of the loop

At present, the servo motors and drivers commonly used in the industry have low integration and cannot meet the high-performance requirements of multi-axis servo motor linkage and coordinated control of optical fiber winding machines.
