Hardware Implementation of Field Oriented Control for Three Phase Machine Drives

This paper presents a high switching frequency FPGA implementation of Maximum Torque Per Ampere (MTPA) and Flux Weakening which are branch of Field Oriented Control (FOC) method 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 was implemented using Space Vector Modulation (SVM) technique. The user interface module was designed to provide real-time torque-time, speed-time, and current-time plots for the user. This interface runs on the PS part of the FPGA and interacts with the user through a UART. The entire system has been verified through simulation.
