Field Programmable Gate Arrays (FPGA) has gained attraction in the field of Industrial automation and is becoming more popular in motor control applications due to its robustness and customizability. The use of FPGA provides outstanding hardware design flexibility. This further enables implementation of a fully customizable peripheral set and also helps to meet the increasing performance requirements.

The paper covers the use of Xilinx Kintex 7FPGA based implementation of close loop control system. The close loop system controls the speed of Three-Phase Brushless Direct Current (BLDC) motor, by using feedback from three hall sensors. Xilinx Kintex 7 FPGA based speed controller of brushless DC motor system is designed and implemented using PID algorithm. The design is implemented using VerilogHardware Description Language (HDL). As FPGA supports reconfigurable computing and provides a facility of on-chip parallelism, good operational performance was achieved.
