N2 - This paper investigates various control centric characteristics of a 3DOF model of an air-breathing hypersonic vehicle. The model of interest is characterized by significant coupling, instability, non-minimum phase dynamics and a large minimized condition numbers (and relative gain elements) near desirable bandwidths of operation. Due to the ill conditioning of this problem, obtaining desirable control properties at various loop breaking points (specifically, the error and the controls) is a non-trivial undertaking. We use a Weighted H∞ Output Feedback Mixed-Sensitivity approach – one that exploits input disturbances in the generalized plant as well as the reference commands. Including reference commands and input disturbances within the generalized plant gives us a design framework to achieve good properties at the error and the controls.
