摘　　要：三相维也纳(Vienna)整流器采用PI控制时参数选择复杂且需解耦及多次坐标变换,不利于数字实现,因此提出一种滑模控制与多比例谐振控制相结合的控制策略。该控制策略的电压外环由滑模控制,输出电压快速,鲁棒性强;而电流内环设计结合整流器数学模型在αβ坐标系的无耦合特性,采用多PR模块,能进一步抑制高次谐波,使电流总谐波失真更低。在MATLAB/Simulink中搭建仿真模型证明了该控制策略的有效性和优越性。When PI control is used for three-phase Vienna rectifier,parameter selection is complicated and requires decoupling and multiple coordinate transformation,which is not conducive to digital implementation.In this paper,a control strategy combining sliding mode control with multi-PR control is proposed.The outer voltage loop is controlled by sliding mode,and the output voltage is fast and robustness.The design of the current inner loop combines the uncoupling characteristics of the mathematical model of the rectifier in theαβcoordinate system.The use of multiple PR modules can further suppress high-order harmonics and reduce the total harmonic distortion of the current.The simulation model in MATLAB/Simulink proves the effectiveness and superiority of the control strategy.
