Real-time BLDC motor control using the Stellaris LM3S8962 microcontroller

The paper presents a brushless direct current (BLDC) motor closed loop control application using the Texas Instruments (TI) Stellaris LM3S8962 microcontroller. The motor speed can be controlled and monitored in real-time using the CAN module of the LM3S8962 microcontroller and a graphical user interface (GUI) implemented in Matlab. The data transfer between the microcontroller and the PC is done using a USB to CAN converter. The application presented in this paper also allows the remote control of the BLDC motor using the Ethernet controller of the LM3S8962 microcontroller. For speed control a PID controller with anti-windup is implemented on the Stellaris LM3S8962 microcontroller.
