Digital Controller of BLDC Motor Using DSP

DSP를 이용한 BLDC 전동기의 디지털 제어기

This paper presents the software control of a brush-less DC motor. Not only speed and current controls but also a real-time identification of the motor parameters can be implemented by software using the digital signal processor (DSP) TMS320F240. The DSP Controller TMS320F240 from Texas Instruments is suitable for a wide range of motor drives. TMS320F240 provides a single chip solution by integrating on-chip not only a high computational power but also all the peripherals necessary for electric motor control. The main benefits are increased system reliability and cost reduction of the overall system. The present paper describes how a speed controlled brushless DC drive can be implemented using TMS320F240.
