Abstract—This work describes a novel modeling and simulation
approach of brushless DC motor control system depended on
analysis of it’s mathematical model. The brushless DC motor
ontology model, the voltage type inverter circuit model, the
hysteresis current tracking comparative model and the PID speed
controller model were constructed in the Simulink environment
of Matlab. S-function was used in modeling to make the model
simple and reflecting its mathematical model and the essence of
running principle in the furthest way. Simulation results show
that the modeling method is completely feasible, and simulating
efficiency is high as the simulating model running quickly. The
modeling approach provides a new idea for the model
construction and has important application value for the
research and design of brushless DC motor control system.
