A Control System Designed Based On TMS320F2812PGFA For Terms-Translational Motor

The motion control is a joint area in engineering practice based on electromagnetic and other driving technology. The rotor of the motor translates only relatively to the stator of the motor. By this way, the weaknesses of long operating distance, slow response velocity, unstable working point when the velocity is low and small output moment are all avoided. All of those weaknesses are brought in when the rotor of the traditional motor rotating a cycle relatively to its stator. Now the digital controlling system which used the micro processor, general computer, DSP controller have already been the mainstream of the recent speed- adjusting technology.With the development of the DSP technology, and its incomparable advantage in the signal processing, it has been an inevitable trend that the DSP used as the main controller in motor control. The strong ability to arrange the events of TMS320F2812PGFA has made convenient to control the system. A new movement control system for a kind of terms-translational motor has been developed in this paper, a control system based on the embedded processor TMS320F2812PGFA was designed to generate 4 different PWM signals to control the motor accurately. Furthermore, it also supplied the data by collecting the flux and current of every part respectively from inductance and current-sensor to compute the motor torsion in the following process. From this paper, we also designed the driving program and system controlling software, as well as the driving circuitry. It also realized serial port communicating program. It can send the data to computer in time or receive the controlling command sent by the computer.After the command data are processed by the DSP, the data control the motor in real-time.
