Position Control of a Servo Motor using FPGA

Abstract

A new method of controlling position of Servo motor on Field Programmable Gate Array (FPGA) is adopted. In this paper we present the design, implementation and experimental validation of a position control of a servo motor using FPGA. A Potentiometer is used to vary the Pulse Width Modulation (PWM) which determines the motor direction.  The programming is done using Verilog HDL and the type of control board used is XILINX Vertex 4 FPGA. The results show that the position of the servo motor was controlled efficiently.
