Current predictive control for three-phase voltage source inverter based on Labview FPGA module

Abstract

In this paper, a current predictive control for three-phase voltage source inverter development on Labview platform is presented and realized. It uses the FPGA (Field Programmable Gate Array) module of NI company PAC (CompactRIO 9073) as the calculator to finish the model predictive algorithm. As the FPGA coprocessor can work in parallel structure, it finished the algorithm in nanosecond and output control signal immediately. Compared to normal predictive control using DSP coprocessor, this can realize deadbeat predictive well without any additional deadbeat compensation algorithm. By using Labview FPGA module platform, it became not difficult to program complex algorithm in FPGA.
