This paper presents a Xilinx Field Programmable Gate Array (FPGA) based speed control of AC Servomotor using sinusoidal PWM technique. Xilinx FPGA is a programmable logic device developed by Xilinx which is considered as an efficient hardware for rapid prototyping. It is used to generate 50 Hz sine wave, the triangular wave and the sinusoidal PWM signals. The sinusoidal pulse width controls the speed of Motor. The proposed control scheme has been realized using Xilinx FPGA SPARTAN XC3S400 and tested using SM115 model Alternating Current (AC) servomotor. The result provides a controllable speed with satisfactory dynamic and static performances.
