Application of DSP in the Control of Electromotive Well-automatic Discharge Car Using Frequency Conversion Power

The electric principle of 154 ton electromotive wellautomatic discharge car is introduced,and the control of it by the control system which takesTMS320F2812 as core is summarized. It mainly discusses that how TMS320F2812 tests effective synchronous signal through hardware,and synchronous phaseshift triggering signal is produced making use of software,and control target is converted into the output of synchronous phaseshift triggering signal,to realize the control of TMS320F2812′s excitation timing to the 154 ton electromotive wellautomatic discharge car. The experiment result indicates that this method eliminates effectively the influence of frequency conversion power on 154 ton electromotive wellautomatic discharge car.
