According to the requirements of ADS project for superconducting magnet power supply system, a controller with high stability for superconducting magnet power supply system is designed, and it mainly consists of optical fiber module, digital to analog converter (DAC) and analog to digital converter (ADC) circuit. The DAC based on digitally controlled potentiometer (DCP) and field programmable gate array (FPGA) can achieve high stability control of superconducting magnet power supply, and the value of current can be given by the DAC. The output stability of this DAC can be more than 2×10-5, which can fully meet the requirement of 5 × 10-5 for superconducting magnet power supply. The test data of the system is given, which verified the rationality and reliability of this design.
