SuperKEKB is the upgrade of KEKB, the asymmetric energy electron-positron collider for the B-factory experiment in Japan. It aims at the 40-times higher luminosity than the world record by KEKB. The KEKB control system has been built based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ these frameworks while we implement new features for the successful operation at such a high luminosity. As the commissioning of the SuperKEKB main storage rings is scheduled to start in 2016, the construction of the control system is now in the final phase. We have upgraded and reinforced the network system, server computers and operator consoles. Most of the VME-based IOCs (I/O Controllers), which has been widely used in KEKB, are upgraded while the PLC-based IOCs are also widely introduced. The new timing system has been developed in order to handle the complicated injection scheme of the SuperKEKB accelerator complex efficiently. The new beam abort trigger system and the new beam gate control system have been developed, and so on. The construction status of the SuperKEKB accelerator control system will be presented.
