Abstract

This paper describes the control system analysis and design for the three principal axes of the 2.5 mts SDSS Telescope. The telescope requirements are good tracking performance with errors lower than 165 marcsec rms in the speed range between 0 to 45 arcsec/sec for all the axes. The pointing error is about 2 arcsec rms per axis for a maximum absolute value of 5 arcsec. The telescope has the additional requirement of slewing, between tracking areas, with maximum speed of 3 degree/sec.
