Brushless DC motor speed control system Simulink simulation

摘要

According to the mathematical model of a brushless DC motor, using MATLAB / Simulink to build various independent functional modules, and integrated into the simulation model of brushless DC motor control system. The system uses the double loop of control mode, including the inner current loop and the outer speed loop, to ensure that the motor is performance well in the high and low speed, and system has start fast, flexible control, robustness and other advantages. By conducting the two simulation experiments of tracking the speed and keeping the speed stability, we preliminarily verify the effectiveness and reasonable of the system modeling method and the feasibility of the control system design, simulation and setting parameters can also be made to optimize the actual controller control and commissioning reference.
