针对三相电压型PWM整流器交流侧电感值实际控制系统中存在误差，往往忽略掉耦合项，以及系统参数变化影响整流器的动、静态性能等问题，提出了一种新型的双闭环控制策略。其中电流内环采用同步旋转d?q坐标系下无电感L参数的解耦控制与内模控制相结合的方法，电压外环采用滑模控制，在Matlab中利用Simulink工具箱搭建三相电压型PWM整流器数值仿真数学模型，数值仿真结果表明系统仍获得了较好的动、静态性能，鲁棒性强。并通过实验平台验证该控制策略的正确性和优越性。

A novel dual closed?loop control strategy is proposed in view of the problems that AC inductance value of the three?phase voltage?source PWM rectifier exists error and often ignores the coupling term in the actual control system,and the change of system parameters affects the dynamic and static performance. The hybrid mode of decoupling current control without exact value of the boost inductor in d?q synchronous frame and internal model control is adopted in the current inner loop. The sliding mode control is adopted in the voltage outer loop. The three?phase voltage?source PWM rectifier simulation model is build with Simulink toolbox in Matlab. The simulation results show that system can still obtain the excellent dynamic and static perfor?mance. And the system robustness is strong. The validity and superiority of the proposed control scheme were verified by experi?mental results of the physical platform.
