Currently accelerator control systems adopt distribution architecture and axe developed with integration tools, such as EPICS, TANGO and SCADA. The digital controller based on FPGA, DSP is widely used in accelerator controls and embedded EPICS IOC is a hot point. On the software side, laboratories have built their software development environments and the open sources Eclips, Abeans serve software development too. The high availability research is a challenge in the control world. The paper describes accelerator controls. and progress of correlative technologies.
