Design and implementation of a motor control module based on PWM and FPGA for the development of a UAV flight controller

This article demonstrate how the Top Down design of the navigation controller implemented in the UAV, "Drone Bosco," was made. The development of the pulse width modulation driver used in the control of the drone´s motors with its coding and implementation is presented. This article highlights the reasons behind the use of a FPGA with hardware descriptive language and explains how its features helped us achieve our objective. The lab results at the end of the article illustrate the functioning of the module and how it compares to a sequential embedded system based module.
