Abstract
Field programmable Gate Arrays are extensively used in the field of Industrial Automation especially in Speed
control of BLDC motor for its hardware design flexibility. This paper discusses the digital Pulse Width
Modulation (PWM) control implemented in FPGA for a BLDC drive in motoring mode of operation. The design
and simulation of closed loop control system using PID algorithm is done on Xilinx Spartan 3E FPGA kit. The
system controls the speed of three phase BLDC by using feedback from hall sensors. Simulations are done
using VHDL with Modelsim software.
