Abstract

This paper proposed a method which was based on DSP and FPGA and applied in the fully digital and high-performance permanent magnet synchronous motor (PMSM) AC servo system. In the system, the position loop control combined PI control and feedforward control was implemented by DSP unit, while the speed loop and current loop control were implemented by FPGA unit. Since FPGA provided a kind of hardware design scheme for the control system, it had the features of a special control IC. The functions of vector control algorithm, velocity and current sampling, space vector pulse width modulation and PI algorithm were included in the special control IC. In the meanwhile, it also provided host communication interfaces that could realize the real-time modification of the control parameters in the IC. Finally, the experimental results indicate that this system has high-speed response and well static state control performance.
