Redundancy motor servo control system

The invention discloses a servo control system adopting a multi-redundancy motor. The disclosed control system comprises a processor A, a processor B and a dual-port RAM, wherein the dual-port RAM is connected with the processor A and the processor B; the control system realizes the capability of acquiring working data of a host processor in real time by a backup processor based on a data transmission method of a dual-port RAM (Random Access Memory) and a three-closed-loop control method; and meanwhile, a time-sharing PID method is adopted, so that the problem that the control performance of the motor is reduced when the processor is switched is solved. 本发明公开了一种采用多余度电机伺服控制系统。所公开的控制系统系统包括处理器A、处理器B和双端口RAM，所述双端口RAM连接处理器A和处理器B；控制系统基于双端口RAM的数据传输方法和三闭环控制方法，实现了备份处理器实时获取主机处理器工作数据的能力；同时采用分时PID方法，解决了处理器切换时，电机控制性能下降的问题。
