Dynamic Load Alleviation in Wake Vortex Encounters [PDF]
Journal of Guidance, Control, and Dynamics, 2016 This paper introduces an integrated approach for flexible-aircraft timedomain\ud aeroelastic simulation and controller design suitable for wake encounter\ud situations. The dynamic response of the vehicle, which may be\ud subject to large wing deformations in trimmed flight, is described by a\ud geometrically-nonlinear finite-element model.

Allocation of distributed flaps for gust load alleviation [PDF]
2017 IEEE Conference on Control Technology and Applications (CCTA), 2017 Increasing the number and functionality of control surfaces provides great potential to improve aircraft performance. This, however, complicates the design of the control allocation system commonly used for flight control. A novel method for linear control allocation is presented which allows considering an arbitrary number of frequency dependent ...
