Operational spacecraft undergo substantial mass property and configuration changes
Chapter 0, Problem AP9.1(choose chapter or problem)
Operational spacecraft undergo substantial mass property and configuration changes during their lifetime [25]. For example, the inertias change considerably during operations. Consider the orientation control system shown in Figure AP9.1. (a) Plot the Bode diagram, and determine the gain and phase margins when con 2 = 15,267. (b) Repeat part (a) when a),,2 = 9500. Note the effect of changing w 2 by 38%.
