Abstract: Targeting at the development demand of current numerical control system for high power density drive and control system, a multiaxis AC permanent magnet synchronous motor (PMSM) servo system was presented based on digital signal processor (DSP) and programmable logic devices (FPGA). Firstly, the hardware was introduced in detail, which included power circuit, detection circuit, protection circuit, control circuit, communication circuit, etc. Secondly, the methods of software implement and the signal sampling time point selection were presented. With the space vector control method，the servo system makes full use of centralized control and hierarchical process design, and has the position, speed control and current control function．Experimental results show that the system has a advantages of realtime,  high control precision and excellent dynamic response.
