摘要
详细介绍了一种应用于大型天线系统的多电机同步控制系统的设计。可编程计算控制器PCC通过CAN总线与驱动器DC590通信,采集驱动器电流反馈,经同步消隙控制算法后向各支路驱动器输出速度控制命令。驱动器采用独立的速度环,在50 m及65 m射电望远镜天线伺服系统应用中取得了良好的伺服控制精度。PCC可以根据驱动器状态灵活配置驱动器工作组合,提高了系统的可靠性。
This paper introduces the design of a multi-motor speed synchronization control for large radio telescope system. The system implements the communication between PCC (Programmable Computer Controller) and servo drives (DC590) using CAN bus. The PCC obtains current feedback from each servo drive and sends velocity command to each servo drive. The synchronization control algorithm which consists of independent rate loops is implemented by PCC. Satisfactory servo control accuracy has been achieved in 50 m and 65 m radio telescope antenna system. Servo drives are configurable,so the reliability of the servo system is improved greatly.
