摘　　要：针对工业CT运动平台的控制问题,尤其是两轴同步运动的问题,研究了运动平台的控制方式,尤其是同步运动轴的同步控制方式。基于欧姆龙Sysmac自动化平台,设计了控制系统,包括硬件组成、通信协议、轴的配置、程序的设计。为了满足高精度的定位要求,对于运动轴采用了全闭环控制;针对同步运动问题,利用欧姆龙PLC内置的电子齿轮功能,设计了2种同步运动模式,编写了程序;结合非同步运动,利用运动平台对其运动性能和定位精度进行了测试。研究结果表明:该系统单轴定位准确,同步轴之间同步运动位置偏差仅为0.8μm,明显优于其他模式,系统满足使用要求。Aiming at the control problem of industrial CT motion platform,especially the requirement of two-axis synchronous motion,the control system was studied,especially the synchronization motion was studied.A control system was designed based on the OMRON Sysmac automation platform,that included hardware,communication protocol,axis configuration and program.In order to satisfy the high-precision positioning requirements,full closed-loop control was adopted for the motion axis.Taking advantage of Omron PLC′s built-in electronic gear function,two kinds of synchronous motion mode were designed,and programs were written.The motion performance and positioning accuracy were tested on the platform with non-synchronous motion mode.The results indicate that the single-axis positioning is accurate,and the position deviation of synchronous motion between the synchronous axes is 0.8μm,better than other modes.The system satisfies the requirements.
