Design of dual-PMSM synchronous control drive

To meet the demands of modern AC servo systems for high-power and high-precision, a new drive that synchronizing two Permanent Magnet Synchronous Motors (PMSM) is designed based on DSP (Digital Signal Processor) and CPLD (Complex Programmable Logic Device) in this paper. The structure of the dual-PMSM synchronous control drive is detailed described. The hardware circuits and the software with the function of synchronous control are also designed. The experimental results show that the synchronous control drive has good performance in terms of running reliably and tracking precision for synchronizing two motors. This device has a broad perspective for popularization.
