XMOS BLDC and PMSM Motor Control Platform

Advanced Motor Control

Stable release:	2.0
Status:	Design Ready
Maintainer:	https://github.com/DavidNorman

Firmware and documentation to go with the XMOS XK-MC-LVM2 and XP-MC-CTRL-L2 Motor Control Development Kits.

Key Features

• Dual Axis Field Oriented Control (Speed Control) of PMSM Motors
• Dual Axis Trapezoidal Commutation (Speed Control) of BLDC Motors
• Up to 142kHz inner loop performance
• Complementary PWM up to 48 KHz at 11-bit complementary PWM resolution
• CAN or Ethernet interface with LabView GUI, or use push-button control
• Component based approach to motor drive and communications interfaces

Firmware Overview

The software is split into modules and applicatons, as describes below:

Type	Name	Description
Application	app_dsc_demo	Fully functional dual axis FOC speed control of two LDO PMSM motors
Application	app_control_board_demo	Standalone control board demonstration example
Application	app_basic_bldc	Simple dual axis motor BLDC trapezoidal commutation example
Application	app_power_board_test	Manufacturing test sw for power board
Application	app_control_board_test	Manufacturing test sw for power board
Host Software	gui	LabView gui for ethernet or CAN control of dev board from PC
Component	module_dsc_adc	Interfaces to various external ADCs for current sampling
Component	module_dsc_blocks	Inner loop transforms (e.g. park, clarke, PI)
Component	module_dsc_comms	Code to bridge the ethernet/CAN into the main code loop
Component	module_dsc_display	Module for operating the LCD and buttons
Component	module_dsc_hall	Interface to Hall sensors (only used for BLDC commutation)
Component	module_dsc_qei	A quadrature encoder interface

Required Modules

In addition, the code imports and uses the following components from the xcore github repos:

Type	Name	Description
Component	git://github.com/xcore/sc_ethernet.git	Ethernet MII module
Component	git://github.com/xcore/sc_xtcp.git	TCP/IP stack
