“…Nevertheless, the conventional GS involves the lack of guaranteed global robustness and stability [4]. The reentry flight conditions change rapidly, which makes this method impractical [5]. Moreover, the point designs of gain scheduling are manpower intensive and highly time consuming [6].…”

This paper presents the finite-time attitude control problem for reentry vehicle with redundant actuators in consideration of planet uncertainties and external disturbances. Firstly, feedback linearization technique is used to cancel the nonlinearities of equations of motion to construct a basic mode for attitude controller. Secondly, two kinds of time-varying sliding mode control methods with disturbance observer are integrated with the basic mode in order to enhance the control performance and system robustness. One method is designed based on boundary layer technique and the other is a novel second-order sliding model control method. The finite-time stability analyses of both resultant closed-loop systems are carried out. Furthermore, after attitude controller produces the torque commands, an optimization control allocation approach is introduced to allocate them into aerodynamic surface deflections and on-off reaction control system thrusts. Finally, the numerical simulation results demonstrate that both of the time-varying sliding mode control methods are robust to uncertainties and disturbances without chattering phenomenon. Moreover, the proposed second-order sliding mode control method possesses better control accuracy.

“…Previous work on the application of H-infinity FDI techniques to re-entry include (Augustin et al, 1999), where reaction control system failures were considered during the early re-entry phase of the Shuttle vehicle, and (Castro et al, 2006), which considered the Shuttle vehicle operating in the transonic region of the re-entry trajectory, with actuator failures considered. The work detailed herein represents a maturation of the work reported in (Kerr et al, 2008).…”

This paper describes the application of a fault diagnosis algorithm in a simulation campaign conducted with the Advanced Technologies Testing Aircraft (ATTAS). To provide a realistic fault scenario suitable for in-flight testing, the effects of actuator rate saturation were considered to be the result of faults acting on the ATTAS. Fault diagnosis algorithms were designed for these faults using H-infinity fault detection and isolation (FDI) filter synthesis tools and online thresholding algorithms. These fault diagnosis algorithms were assessed in an incremental validation campaign by first using the ATTAS high-fidelity nonlinear model, and then the German Aerospace Center (DLR) ATTAS flight simulator. In-flight data from previous flight campaigns investigating methods to alleviate rate saturation effects was used to assess the performance and robustness of the algorithms under real flight conditions.
