Vector control, direct torque control and other advanced control theories have been put forward, and the microprocessor controller and the update especially digital signal processor (DSP) appear, makes theory into practice. Intelligent power module and space vector pulse width modulation (SVPWM) technology appear, greatly improved the motor control performance. This paper focuses on the function of the powerful DSP, intelligent power module and advanced SVPWM technology to achieve permanent brushless dc motor of the open loop control. Introduces the hardware platform based on DSP control of the component. Analyses the SVPWM technology principle, produce PWM waves of the control algorithm and the realization of the program, and the last in the DSP control platform on the control performance is validated. This paper all the hardware circuit design and programming TMS320F2806 based on a digital control system. Hardware circuit of the power supply circuit, monolithic DSP minimum system such as the main part of the circuit is after the actual soldering and debugging. The software design o
