ANTENNA ROTATOR DESIGN AND CONTROL

This paper consists of design and development of rotator for antenna positioning
according to the desired azimuth and elevation. The rotator is to have the capability to be
manually controlled (press button switch) or software driven. It should incorporate safety
stop switches as well as position and speed sensors in order to achieve smooth movement
and correct stopping position.
The basic principle needs to be studies are speed control using the microcontroller, exact
angle of position movement, and stoppable motor can be done in time due to emergency
cases. As larger load is applied to the device, the large inertia will need to be compensated
to achieve a good dynamic. For position and speed regulation in antenna system, a DC
motor will need to be used as the primary driver along with the appropriate in mechanical
coupling. The appropriate and suitable rotator need to be chosen for better result in speed
and position.
