Abstract

This paper discusses the pointing and control of NASA´s next generation tracking and data relay satellite (TDRS) antennae using classical design techniques and modern multivariable analysis techniques. Classical loop shaping realizes a design with good single loop stability margins. Multiloop stability margin analysis verifies stability robustness against sensor parametric uncertainties, modal frequency shifts and gain/phase variations of the integrated control system
