High Performance Torque Control of Brushless DC Motor Drive based on TMS320LF2407 DSP Controller

چکیده مقاله

Brushless DC (BLDC) motor is attracting much interest due to its high efficiency, good performance and ease of control for many applications. This paper presents the design and implementation of a torque controller for a Brushless DC motor drive using the TMS320LF2407A digital signal processor (DSP) produced by Texas Instruments. Firstly, a theoretical analysis of a BLDC motor drive is presented and the validity of the proposed analysis is verified by simulation. The torque is controlled via current regulation directly. Then, hardware and software details of the system are explored. Finally, an experimental system included by a BLDC motor, DSP control board, inverters, rectifier is set up to validate the theoretical ones.
