摘　　要：重复控制器可以实现三相逆变器输出波形的精确控制,且稳定性好、抗干扰能力强。基于三相逆变器的数学模型,以逆变器输出电压控制为例,提出了在αβ坐标下重复控制的现场可编程门阵列(FPGA)实现方法。采用多个浮点运算IP核实现并行计算,使用FIFO实现大容量数组的存储和更新,将极大提高重复控制器运算的速度,从而可以提高输出电压的波形质量,减小滤波器的体积;最后通过仿真和试验验证了控制算法的可行性。Repetitive controller can achieve precise control of three-phase inverter,and it has better stability and robustness. Based on the model of three-phase inverter,this paper proposed an implement method of repetitive controller in αβ coordinate using FPGA to regulate output voltage. In this method,more than one floating-point operator IP cores are used for parallel computing and FIFO IP cores are used to achieve large capacity storage and data updating. This will greatly enhance the computing speed and then improve the quality of the output voltage waveform. The simulation and experimental results verifiy the effectiveness of the control strategy.
