英文摘要：

Based on the principle of Superconducting Magnet Energy Storage （SMES） and the usage of the rectifier with control mode of Pulse Width Modulation （PWM）, a kind of mathematical model, in which a SMES is controlled by a three-phase voltage source PWM rectifier, is established and a PWM rectifier double close＆loop control system with the control mode of fee＆forward decoupling is designed. Simulation results using Matlab/Simulink software reveal that such a system has some advantages such as quicker response and higher stability compared with conventional system.
