英文摘要：

In order to satisfy the scientific research demands of the compact pulsed high magnetic field facility（CPHMFF） in the areas of biology,medicine and environment protection,a 20 Tesla scale CPHMFF was designed and realized.The components of CPHMFF was introduced,the design principle and an example of protective inductor were given.The details of control system of CPHMFF were emphasized.Two control modes of manual and automatic were provided.The control system consisted of control software and local control unit,which were connected through optic fiber.Based on the mechanism of finite state machine adopted in communication protocol,the control system implemented the functions of process control,switches status＇ monitoring,measurement data sampling and displaying in real time.The experimental results show that the ratio linearty of discharge voltage to peak field is better than 2 % and the repeatability error of peak field under a same discharge voltage is within 1 %.This compact pulsed high magnetic field facility and its control system meet the requirements of design.
