Implementation of Vector Oriented Control of DFIG based on FPGA

Control strategy is indispensable in the use of doubly fed induction generator (DFIG). Vector oriented control (VOC) is a control strategy that has been tested by many scholars in DFIG on software. Field-Programmable Gate Array (FPGA), with the powerful capability of parallel computing and satisfying clocking frequency up to 200MHz, has widely applications in the high-speed data processing. Moreover, System Generator, as a tool developed by Xilinx, is a Simulink-based toolkit for FPGA developers. Thus, this paper implements VOC on FPGA by using System Generator. The simulation result shows that FPGA works well on VOC under the clocking frequency of 100MHz. This research solves the timing problem of loop design in System Generator and lays the foundation of real-time simulation of DFIG.
