Brushless DC Motor Closed Loop Control System Based on DSP

Abstract

Abstract: This paper introduces a set of brushless DC motor closed loop control system based on TMS320f2812, hypogyny machine adopts DSP (Digital Signal Processor) as the core digital processor, photoelectric encoder as the feedback element, the motor speed achieves closed-loop control precision. This paper adopts intelligent PID algorithm in the position and speed control, and also realizes the simulation in Matlab/Simulink to increase the stability of control system, shorten the reaction time, and improve the system accuracy.

Key words: TMS320F2812, closed loop control, PID
