Parametric Robustness Analysis for Cassini Spacecraft Using the LMI Approach without Frequency Sweep

Abstract

A generalized Popov multiplier theory enables one to analyze system robustness with mixed real/complex parameters, repeated uncertainties, and multidimensional block uncertainties. Using the Cassini spacecraft thrust vector control (TVC) system as a design case study, modern robust control theory has been applied to the real flight project.
