A brushless DC motor speed control system based on DSP controller

摘要

In this paper, the control system of brushless DC motor is designed to use the TI company's digital signal processor TMS320F2812 as the main control chip. Design for hardware of the system is as follows : drive circuit, voltage and current detection circuit, etc. Software designed in DSP software development environment Code Composer Studio. The C language and assembly language are used for mixing programming. The system realizes brushless DC motor speed control. Control method is fuzzy PID control. And thanks to the fuzzy PID control algorithm, dynamic and static performance and robustness of the system have been greatly improved.
