Design of Control System for Brushless DC Motor Based on TMS320F28335

As we all know, brush less DC motor, which has been widely used in industrial control fields, has the characteristic of simple, reliable and easy to maintain, as well as high efficiency without mechanical change, and easy-to-be high-capacity, high speed, etc. TMS320F28335, which is the newest 32-bit float point DSP produced by TI company, is the best DSP chip in the domain of motion control. On the basis of the summary for the development and application of brush less DC motor speed-variable system, this thesis introduces a control system which uses TMS320F28335 to control the commutation and the speed of BLDCM. The basic structure, operational principle and design method of this system are set forth in this thesis. The thought of hardware design and software programming is introduced as well.
