BLDC Motor Control with Cascade Structure Utilizing ARM MCU

Abstract

In this article is presented the own application structure of a BLDC motor drive demonstrator. This demonstrator is made for the desirables of R3-PowerUP project advertised by the ST Microelectronics. Therefore, mostly ST devices are used especially STM32 ARM microcontroller. The article describes the application structure, used drivers and peripherals and description of implemented cascade control structure. As a result, step responses of both control loops are presented in the form live variables obtained from MCU.
