摘　　要：本文详细介绍了1种应用于大口径天线的多电机同步控制系统。可编程计算机控制器PCC通过POWERLINK总线同时与多台驱动器Baumuller4400通信,采集驱动器实时电流,经力量均衡及力偏消隙算法后,同步叠加不平衡电流控制指令到各支路驱动器电流环中。系统采用独立速度环和多组合电流环,在大型射电天文望远镜伺服控制系统中取得良好的控制精度。This paper introduces the design of a multi-motor synchronization control for large antenna.The system implements the communication between PCC(Programmable Computer Controller)and multiple drives(Baumuller4400)using POWERLINK bus.The PCC obtains current feedback from each drive and sends current command after the force balance and gap elimination to each drive.Contral precision of this system which consists of independent speed loops and multitudinous current loops have achieved greatly in large radio telescope system.
