Abstra::t—As We all know, brushless 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 brushless
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.
