【 摘 要 】

Aiming at the problem that the long-distance transmission of CAN bus in the servo control system is susceptible to electromagnetic interference, a servo control scheme based on optical fiber CAN bus was proposed to solve the problem of stable and reliable communication of CAN bus. Firstly, the paper introduced the architecture of the distributed servo control system and the existing problems; After that, the working principles of the twisted-pair CAN bus interface and the optical fiber CAN bus interface were analyzed; Then the servo control system and control strategy based on the optical fiber CAN bus were designed; Finally, a field experiment was carried out, and the experimental results indicated that the scheme had good real-time communication and reliability.
