History-Aware Control Barrier Functionals with Nonsingular Fading-Memory Kernels
Ege C. Altunkaya, Esra Demir, Murad Abu-Khalaf +1
Safety-critical protection often depends not only on the state and physical limits of the system, but on how that state evolved over time. Here, the safety margin measures the rema…
TANGO-VIO: Triangulation-Aware Navigation with Guaranteed Feature-Observability for Visual-Inertial Odometry
Abdülbaki Şanlan, Ege C. Altunkaya, Hasan T. Bağci +2
In vision-aided navigation and visual-inertial odometry, the quality of triangulated three-dimensional feature positions is a fundamental prerequisite for state estimation accuracy…
Enhanced Flight Envelope Protection: A Novel Reinforcement Learning Approach
Akin Catak, Ege C. Altunkaya, Mustafa Demir +2
This paper introduces a flight envelope protection algorithm on a longitudinal axis that leverages reinforcement learning (RL). By considering limits on variables such as angle of…
Innovative Gain Reconfiguration for Active Fault-Tolerant Flight Control: Balance of Stability and Agility
Ege C. Altunkaya, Akin Catak, Emre Koyuncu +1
In this study, a distinct reconfigurable fault-tolerant flight control strategy is addressed for mitigating one of the persistent safety-critical issue, i.e. loss of control trigge…
Loss of Control Prevention of an Agile Aircraft: Dynamic Command Saturation Approach
Ege Ç. Altunkaya, Akın Çatak, Emre Koyuncu +1
The prevention of the loss of control in agile aircraft during the extreme maneuvers is of concern due to the nonlinear aerodynamics and flight dynamics nature of the aircraft in t…
