Build a practical speed feedback control system for DC motor using Microcontroller
February 1, 2021
With a commercially available driver, the speed of a voltage-controlled DC motor can be easily controlled in an open loop according to the duty ratio when a PWM pulse output from MCU is given. The speed is almost proportional to the duty ratio, but this is the case under no-load operating conditions. The limitation of […]
Speed control of DC motors using Microcontroller PWM output [Open-loop control]
January 25, 2021
Using the L-motor of the LEGO® MINDSTORMS EV3, the STM32Nucleo board will actually operate the motor. The EV3 motor has a built-in encoder, so you can not only monitor the speed, but also get feedback for more advanced operation. First, as a starting point for motion control using MCU, I would like to try open […]
