Fuzzy Adaptive Zero-Error-Constrained Tracking Control for HFVs in the Presence of Multiple Unknown Control Directions

This article attempts to realize zero-error constrained tracking for hypersonic flight vehicles (HFVs) subject to unknown control directions and asymmetric flight state constraints. The main challenges of reaching such goals consist in that addressing multiple unknown control directions requires novel conditional inequalities encompassing the...

Study of the bifurcation behavior of the flow around a 2D Ahmed body applied to active flow control systems

This master thesis focuses in the study of the application of active flow control in the transitional regime (Re ≈ 3E3) at the rear part of the roof of a 2D Ahmed body geometry. To do so, the natural bifurcations of the problem (which separate the ordered laminar behavior from the first pre-turbulent chaotic behavior) are studied, and different...
