摘　　要：插入件是上海光源重要组成设备之一,其控制系统主要由高精度电机运动控制、位置反馈、校正线圈电源控制、前端轨道反馈及人机界面等部分组成。为实现以上功能并无缝接入上海光源EPICS控制系统,设计了基于EPICS的插入件控制系统。在此基础上,利用嵌入式EPICS技术将所有EPICS组件嵌入到一台嵌入式控制器中。嵌入式EPICS技术简化了系统结构,方便用户操作和后期维护。经测试和在线运行,该系统控制功能完整,反馈控制实时性高,束流的稳定性得到了提高,为试验站稳定供光提供了保证。Insertion devices are key components of modern light sources such as Shanghai Synchrotron Radiation Facility （SSRF）. The control system of insertion devices is mainly composed of motion control of high precision motor, position feed- back, correction coil power supply control, front-end feedback and human interface. To implement all these functions and enable insertion devices to be interactive with SSRF＇S EPICS control system smoothly, a control system based on EPICS has been de- signed for the insertion devices. Then, all EPICS components have been integrated into one embedded controller by using embed- ded EPICS technology. With this method, the control system architecture has been simplified, which is more convenient for the maintenance. It has been demonstrated that this control system has integrated functions and good real-time feedback characteris- tics. With this control system, the insertion devices can enhance the stability of beam orbit and guarantee high quality of synchro- tron radiation light for the SSRF＇s beam line stations.
