Abstract : This Memorandum describes the drive and control improvements made to the heavy duty precision pan and tilt head previously reported in Memorandum 3691. The drive improvements have resulted in an increased maximum performance for the head to 4R/sq s in acceleration and to 0.85 R/s in velocity. The improvements to the control circuitry have allowed adaption to computer control and two approaches have been assessed which represent two levels of complexity in the control algorithms.
