DSP-based Brushless DC Motor Control System Design

To improving the control performance of brushless DC motor, the paper designs the motor control system with Digital Signal Processor (DSP) and TMS320F2812 as the cores. To reasonably design the control system, the paper, first, presents the double-closed control system tailored for brushless DC motor based on analyzing its control principles, and finishes the system design from the two aspects of hardware and software. Then, it carries out the modeling and simulation experiments on the control system through MATLAB, and analyzes the changes of simulation waveform in the cases of free-load and on-load. The findings verify that the speed control system is of high practical value for the advantages such as stable and quick startup, outstanding speed control performance, and high control precision, thus
