为进一步提高船舶轴带发电机效率，建立基于前馈解耦控制的空间矢量脉宽调制（Space Vector Pulse Width Modulation，SVPWM）整流器的轴带发电机整流系统。采用一种基于电压电流双环控制的三相SVPWM整流器。电压外环与电流内环组成的解耦模块能实现对有功功率和无功功率的解耦控制，使幅值和频率均变化的交流电通过整流变换为稳定的直流电压。给出电流内环和电压外环的比例积分（Proportion Integration，PI）调节器的设计参数。在MATLAB／Simulink上建立仿真模型，验证控制模型的可行性。仿真结果表明，该整流器具有快速的动态响应和良好的稳定性。

To further improve the efficiency of shaft generators,the shaft generator rectification system of Space Vector Pulse Width Modulation (SVPWM)rectifiers based on the feedforward decoupling control is built. A three-phase SVPWM rectifier based on voltage-current double-loop control is adopted. The de-coupling module including an outer voltage loop and an inner current loop can realize a decoupling control of the active and reactive power. Thus,the alternating current with changeable amplitude and frequency can be rectified to the stable direct voltage. The design parameters of Proportion Integration (PI)regula-tor of the inner current loop and the outer voltage loop are given. A simulation model is established by MATLAB/Simulink,and the feasibility of the control model is verified. Simulation results show that the rectifier is of fast dynamic response and good stability.
