Efficient FPGA implementation of field oriented control for 3-phase machine drives

Abstract

This paper presents an FPGA implementation of Field Oriented Control (FOC) method with high switching frequency for 3-phase machine drives. A common architecture has been constructed for both BrushLess DC motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM). For this purpose, the controller module has been implemented by using a hardware efficient algorithm, namely, Coordinate Rotation Digital Computer (CORDIC). The result of this implementation has been compared with the literature, and we claim that this paper's FPGA design has better performance in terms of area and speed with respect to other FPGA-based FOC designs.
