Fig. 4, the above block diagrams are TMS320F28335 DSP board controlled BLDC motor. The MATLAB/SIMULINK platform is integrated by a monitor communication program, as well as the TMS320F28335 DSP controller evaluation applications. Using the PC communication module can be accessible to the TMS320F28335 DSP controller board, execute any of these programs into the applications and use the TMS320F28335 DSP platform to analyze and evaluate the results.
