Abstract

This paper discusses the Digital Signal Processor as the core to the sensorless brushless dc motor control system design method. Based on the back EMF zero crossing of brushless dc motor rotor position detection method and double closed-loop speed regulation control strategy, designs brushless dc motor sensorless control system hardware circuit and program. With the simulation and debugging experiments for the system, it shows that the control method not only simplifies the hardware system structure, but makes the motor efficient and stable operation.
