Abstract: A resolver-based digital AC servo system realized by using field-programmable logic array(FPGA) was proposed. The intact vector control strategy of permanent magnet synchronous motor(PMSM) was described with verilog hardware description language(HDL) and implemented on one-chip FPGA in accordance with the EDA design methodology, this realized the high density and miniaturization of the servo system. In addition, the detailed designs of basic modules such as resolver, vector transformation, PI regulator, SVPWM module were presented. Simulation and experimental results show that the proposed scheme has excellent dynamic and steady-state performance.
