“…While the method requires less storage and is more capable than a trajectory database approach, V&V of such a system is more challenging due to a lack of guaranteed convergence. More capable and complex trajectory optimization algorithms have been developed [62,63,64,39,38,54] but currently have little chance of passing a V&V process for a flight vehicle for the same reason. For the foreseeable future, any trajectory optimization algorithm that does not guarantee convergence must be backed up by reversion modes that return some feasible trajectory that can be flown in the event that convergence is not achieved.…”

“…IVHM based estimates of the vehicle outer-mold-line can be coupled with fast aerodynamic prediction codes such as DATCOM [37] in order to provide rough, but representative, aerodynamic models of damaged vehicles at flight conditions yet to be encountered. Two nascent approaches to solving this problem have been published in the literature [38,39].…”

“…There have been some recent efforts to develop algorithms for predicting the effects of damage over the flight envelope that will require an extensive amount of information from an IVHM system [39,38]. These prediction methods will require outer-mold-line information, presumably obtained from an advanced IVHM system, to drive fast aerodynamic prediction codes such as DATCOM [37] that can generate estimates of aerodynamic coefficients, which can be blended with temporally local estimates from system identification algorithms.…”

Over the past decade, both NASA and the U.S. Air Force have directed significant efforts aimed at reducing the cost of access to space as well as improving the reliability and safety of launch vehicles. From a guidance and control perspective, efforts have focused on the development of fault tolerant autonomous systems that can recover vehicles from failures or damage when physically possible. The state of the art is summarized in this manuscript and some of the challenges preventing widespread use of some of the techniques are discussed. The integration of vehicle health management systems with adaptive guidance and control is also discussed.

“…The control system design of waveriders should be integrated with the guidance law because any small attitude variation leads to a significant change in the trajectory on the hypersonic flight condition. Therefore, feasible trajectory generation is critical for the design of guidance and control of waveriders to improve the flight performance and minimize the control power [11]. The periodic cruise can typically save more fuel than the steady-state cruise in the hypersonic flight phase [12]; thus, applying the periodic flight trajectory helps improve the hypersonic flight performance.…”

This paper presents a nonlinear trajectory controller with improved performances for a general model of the waverider based on feedback linearization theory and composite nonlinear feedback (CNF) technique. First, a nonlinear controller is presented using the dynamic inversion and CNF technique for the MIMO Model, and the robust stability of the proposed controller is proved. Then, the nonlinear model is established on the basis of hypersonic aerodynamic principle, and the dynamic characteristics are analyzed accordingly, and the periodic trajectory is designed and optimized in combination with a fuel optimization problem. Furthermore, the nonlinear controller is applied to the trajectory tracking of the waverider model, and the general design steps are provided the flight controller using this nonlinear control method. Finally, an illustrative example is given to verify the effectiveness of the nonlinear controller of the waverider, and the flight performances are improved accordingly, including system stability, robustness, and tracking ability.
