1.0 Title: Antenna Azimuth Position Control System
2.0 Objective:
The objective, of the lab is to analyze and design a control system for the antenna
azimuth position using MATLAB and SIMULINK.
3.0 Introduction:
A position control system converts a position input command to a position
output response. Position control finds widespread applications in antennas,
robot arms, and computer disk drives. The radio telescope antenna in Fig. 1 is
one example. The purpose of this system is to have the azimuth angle output
follow the input angle. The input command is an angular displacement. The
potentiometer converts the angular displacement into a voltage. Similarly, the
output angular displacement is converted to a voltage by the potentiometer in
the feedback path. The signal and power amplifiers boost the difference between
the input and output voltages. This amplified actuating signal drives the plant.
The system operates to drive the error to zero when the input and the output
match, the error will be zero and the motor will not run.
