The KEKB project, constructing an asymmetric e⁺e^- collider for B physics in Japan, was officially approved and started in 1994. The KEKB accelerator complex will have more than 50,000 control points along the 3~km circumference of the two rings, the LER and HER. A fast and powerful control system is required to implement sophisticated tuning procedures and feedback loops for the stable operation of KEKB. In addition, such a control system has to be readied in a timely fashion, ie it has to be operational at the first commissioning time of KEKB, which is expected to begin near the end of 1998. The control system is based on the model consisting of distributed equipment control computers and workstations as operator interfaces. Use of EPICS will reduce the load to develop software for the control system. We will report the design of KEKB accelerator control system and status of the development.
