“…The maximum achievable outer loop bandwidth is limited by the vehicle's flexible dynamics as well as the right half plane zero associated with the elevator-FPA map. Additional information about controller parameter selection can be found within [43]. Nominal control system parameter values are given in Table 6.…”

“…A (state dependent) saturation level -associated with FER (e.g. thermal choking and unity FER) -and a useful FER margin definition (one that can be used for the design of control systems for scramjet-powered hypersonic vehicles) was addressed in 43 . Finally, it should be noted that the model offers the capability for addressing linear fuel depletion.…”

Within this paper, control-relevant vehicle design concepts are examined using a widely used 3 DOF (plus flexibility) nonlinear model for the longitudinal dynamics of a generic carrot-shaped scramjet powered hypersonic vehicle. The impact of elevator size and placement on control-relevant static properties (e.g. level-flight trimmable region, trim controls, AOA, thrust margin) and dynamic properties (e.g. instability and right half plane zero associated with flight path angle) are examined. Elevator usage has been examine for a class of typical hypersonic trajectories.
