Simulation and implementation of angular displacement measurement system for antenna positioning

Abstract

An angular displacement measurement system has been designed. System is simulated by using free and open source Scilab. The overall minimum, real time system is designed around an 8-bit cost effective, MCS51 microcontroller 89C2051. A high precision wire wound potentiometer serves as an angular displacement sensor. The digitized sensor output form ADC0804, after processing is displayed on LCD. The system is minimized by connecting ADC in free running mode and LCD in 4-bit mode. The system is tested for measurement of an angular displacement in the range of 0-180°. The results of simulation and the experimental measurements are in good agreement. The system is suitable for angular displacement measurement for antenna positioning.
