ABSTRACT
Along with the development of industrial automation, people on the motor control
system performance demand more and more. 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 of SVPWM procedure mainly using C language to
format, using CCS (C2000) compiled environment in DSP control platform on the actual
commissioning and validation.
