基于双DSP＋FPGA的三相逆变器的设计与实现

摘要

This paper first adopting double closed loop Pl control algorithm designs the three-phase inverter,although can achieve good dynamic performance,but can not meet the steady high quality waveform.With repetitive control based on double closed loop Pl control,and builds the simulation model by matlab.The double DSP+FPGA hardware architecture through the combina-tion of DSP's high speed operation and highly efficient communication capability and FPGA logic processing capability.%首先采用双闭环Pl控制算法设计三相逆变器，虽然能实现高动态特性，不过不能满足高质量的稳态波形。在双闭环Pl的基础上加重复控制补偿，建立MATLAB仿真，将DSP的高速运算及高效通讯能力和FPGA逻辑处理能力相结合，构成双DSP＋FPGA硬件构架，使得在双闭环Pl控制的基础上加上重复控制补偿算法能够在硬件中高效精确地实现。
