This paper presents a design of an FPGA-based AC motor servo control system, which is intended for controlling the rotational speed of a three-phase AC motor through a three-phase inverter using the SPWM control theory. The servo control system consists of four parts： a triangular wave generation module, a three-phase sine-wave generation module, a comparator module and a switch dead-time generation module. All modules of the system are implemented through VHDL and simulated and compiled under the EDA software platform of Quartus II. In order to verify the servo control system, the netlist files generated are configured to the Altera DE2 development board and the simulation and experimental results are shown to verify the viability of the AC motor servo control system.
