DSP control implement of Permanent Magnet Synchronous AC servo motor based on vector control

At present, Permanent Magnet Synchronous Motor (PMSM) AC servo system based on vector control has attracted more and more attentions and the research on it must be a kind of inevitable development trend and focus in the future. This paper is based on DSP TMS320F2812, which is designed for special-purpose on motor control by TI Company, and designs a set of hardware control system for PMSM. The software is written by C2000 assembly language, which realized the speed, current and position loop control. The flow chart of interrupt service routine is available. The simulation results show the excellent performance of DSP control.
