PMSM vector control system design based on TMS320F2812

Based on the theory of PMSM vector control, a PMSM speed control system which modulated on TMS320F2812 DSP chips is proposed in this article. System hardware design which includes DSP control circuits, power driver circuit, the signal detection circuit and protection circuit are introduced. This article describes the system software design and the software flow chart as well. Results show that the system has excellent control performance, which is significant for the application of high precision serve system.
