Based on the analysis of brushless DC motor (BLDC) mathematical model, proposed a new method of brushless DC motor system simulation modeling in Matlab/Simulink, the establishment of an independent functional modules, such as BLDC body module, a current hysteresis control module, speed control module, then the organic integration of functional modules, to build simulation models of brushless DC motor system in order to guarantee fast and effective simulation model using trapezoidal wave counter electromotive force generated piecewise linear method, the system uses double-loop control: speed loop using PI control, current loop hysteresis current control simulation results show the effectiveness of the method, but also applies to verify the reasonableness of the other control algorithms, providing a new actual motor control system design and commissioning. ideas.
