Posted By George smith

To minimize vibrational effects, a telescope is magnetically levitated. This method also eliminates friction in the azimuth magnetic drive system. The photo detectors for the sensing system require electrical connections. The system block diagram is shown. Design a PID controller so that the velocity error
