摘　　要：目的解决传统机械连接方式多电机同步控制存在的机械结构磨损大、控制精度不高等问题。方法基于偏差耦合控制系统结构,与快速非奇异终端滑模控制相结合,提出一种多同步电机速度同步控制策略。结果该算法能够针对电机在不同转速和扰动负载下作出快速响应,减少了扰动对系统的影响,进一步提高了多电机运行时的同步精度。结论该控制算法具有较好的控制性能,能够满足实际生产的需要。The work aims to solve such problems as large wear and low control accuracy of the mechanical structure existing during the multi-motor synchronous control of the traditional mechanical connection. Based on the structure of relative coupling control system, and combined with the fast nonsingular terminal sliding-mode control, a kind of synchronous control strategy for the multi-motor synchronous speed was proposed. The algorithm could rapidly respond to the motor under different speeds and disturbance loads, which reduced the influence of disturbance on the system and further improved the synchronization accuracy during the operation of multiple motors. The proposed control algorithm has better control performance and can meet the needs of the actual production.
