After many research and developments in the fields of magnetic materials and power electronics, their applications to electric drives have increased to a significant extent This thesis presents the model construction of a brushless DC motor via MATLAB/SIMULINK, so that one can evaluate the performance of the BLDC motor control with various control schemes using MATLAB/SIMULINK. The constructed model consists of a BLDC motor dynamics block, a Hall-sensor signals generation block, a back-emf block, and a PWM-generation logic block. In order to evaluate the model, various cases of simulation studies are carried out. The control and PWM-generation logic block then can be transferred to digital hardware circuit in VHDL hardware description language for simulation verification in the MATLAB/SIMULINK environment. Experiment results by using FPGA control are also obtained to verify the correctness of the constructed BLDC model.
