Experimental Validation: Subscale Aircraft Ground Facilities and Integrated Test Capability

Flight Test of Composite Model Reference Adaptive Control (CMRAC) Augmentation Using NASA AirSTAR Infrastructure

“…The elevator results are shown in Figure III. 6, and indicate that for this maneuver the elevator surface activity is similar for both control laws. This is The increased surface activity seen via FFT coefficients is also present in the time histories, as shown in Figure III.9.…”

Diagnostics of Fly-by-Wire Control System/Kompiuteriu Reguliuojamos Valdymo Sistemos Diagnostika

“…Faults in the equipment and software may arise. Very often, some forgotten methods may be helpful in finding these types of faults: the use of address traps, analysis of input/output data structures, or even modification of the system in order to obtain access to asynchronous signals of the system [1]. However, the most difficult for detection and removal are the faults arising at the full load of the system, when the additional interaction of events resulting in the fault occurs.…”

Nonlinear region of attraction analysis for flight control verification and validation

“…This paper applies the nonlinear analysis tools on NASA's Generic Transport Model (GTM) aircraft (Cox, 2009;Murch and Foster, 2007). The GTM is the primary test aircraft for NASA's Airborne Subscale Transport Aircraft Research (AirSTAR) flight test facility (Jordan and Bailey, 2008;Jordan et al, 2006;Bailey et al, 2005). The AirSTAR program addresses the challenges associated with validating flight control law in adverse condition (Murch et al, 2009;Murch, 2008;Gregory et al, 2009).…”
