ABSTRACT
Field Programmable Gate Arrays (FPGAs) are increasingly being used in motor control applications due to their robustness.
The PWM signals are generated using Hardware Descriptive Language (HDL).
FPGA implementation of Pulse Width modulation (PWM) signals provides an economic solution & fast circuit response .
OBJECTIVE
The objective of this project is to design a FPGA based controller for BLDC motor which is an experimental model implementation in which SPWM strategy is the proposed control scheme .
FPGA based speed controller is designed for closed loop operation of the BLDC motor so that the motor runs much close to the reference speed.
Realization is done using FPGA SPARTAN 3A DSP Trainer kit from Xilinx with the help of VHDL programming algorithm.
INTRODUCTION
The voltage is varied by changing the duty-cycle of the base PWM which in turn alters the speed of the Motor.
Employing FPGA to realize PWM strategies provides simple & hardware design and better speed control.
FPGA implementation has the capability of executing several processes in parallel.
