Abstract :
Digital vector control system´s stability is inevitable reduced due to sampling delay, algorithm calculation delay and the PWM output delay. The inherent time delay in the digital control system is analyzed. The complex vector model which is based on single input single output system and root locus is used to analyze the system stability. Then the DSP and FPGA hybrid control system is built which will reduce PWM updating time. Compared to the DSP-based system, the hybrid control system has less delay time. The experiment is based on Permanent Magnet Synchronous Motor (PMSM) to verify the optimization of time delay and prove that DSP and FPGA based control system performs better than DSP-based system.
