Speed Control of BLDC Motor using Sinusoidal PWM using FPGA Mech Project
Introduction
Electric motors are widely used in various applications due to their efficiency and reliability. Among them, Brushless DC (BLDC) motors are becoming increasingly popular due to their advantages over traditional motors, such as higher efficiency, lower maintenance, and improved performance. In this project, we aim to design a speed control system for a BLDC motor using Sinusoidal Pulse Width Modulation (PWM) technique implemented on a Field-Programmable Gate Array (FPGA).
Problem Statement
The speed control of BLDC motors is often challenging due to the non-linear characteristics of the motor. Traditional methods of speed control, such as Direct Torque Control (DTC) and Square Wave PWM, may result in poor performance, high torque ripple, and inefficiency. Therefore, there is a need for a more advanced and efficient speed control technique for BLDC motors.

In the existing system, BLDC motors are typically controlled using trapezoidal or square wave PWM techniques. These methods have limitations in terms of torque ripple, efficiency, and overall performance. Additionally, they require complex sensor feedback systems to accurately control the speed of the motor.
