Software Design of Brushless DC Motor Control System Based on DSP

Brush less DC motor has been more and more widely used in recent years. This paper designed a control system of BLDC motor driver Based on TMS320F2808 DSP, which can realize the closed loop control of current, velocity and position. Customer can set parameters and working mode of the driver with different load and use via the interface on PC, this paper discusses the main modules such as initialization, AD sampling, Hall commutation and RS232 communication module in detail, what´s more, we adopt the anti-windup PID control algorithm rather than traditional PID, as a result, Experimental results show that the system has reached good dynamic performance and static performance.
