Stability Margins,t flutter problem posed in Question 5.3.1. The value of . is a sufficient direct indication of the flutter margin for the nominal system while additional information about the norm bound on the uncertainty is required to derive the robust flutter margin.

Robust Aeroservoelastic Stability of the F/A-18 HARV,onditions. This paper considers the F/A-18 HARV with a thrust vectoring system to direct the flow out of the engine nozzles. This aircraft, shown in Figure 12.1, is sometimes denoted as the HARV-TVCS to emphasize the thrust vectoring control system, but for convenience the additional TVCS notation w

Conclusion,cate the smallest perturbation in dynamic pressure for which the model is not robustly stable to those uncertainties. Correspondingly, nominal stability margins consider only a theoretical plant and may be highly suspect because of errors and unmodeled dynamics. Thus, robust margins provide a higher
