The control system of BLDCM have the characteristics of time-variation, nonlinearity and close coupling. How to achieve the goal efficient and reliable is a problem will be resolved in the paper. This paper presents a new brushless DCmotor drive control system whichadopts the DSP as hardware platform and μC/OS- Ⅱ real -time embedded operating system as software platform. This system fully utilizes the wealthy peripherals and high-speed calculation to minimize the hardware. The time for software design will also be shorter with μC/OS- Ⅱ running in the system.
