Conference Object İha'lar için Gürbüz Takip Denetçisi(Institute of Electrical and Electronics Engineers Inc., 2013) Tanyer, İlker; Tatlıcıoğlu, Enver; Zergeroǧlu, ErkanIn this study, a nonlinear control technique that guarantee exponential output tracking for unmanned aerial vehicles subject to uncertainties in system dynamics and additive nonlinear disturbances is developed. In the literature, dynamic inversion method which is a nonlinear control technique commonly used within the aerospace community to replace aircraft dynamics with a reference model. Dynamic inversion and robust control methods were usually utilized together to compensate for the uncertainties and ensure output tracking. Review of the literature highlights the fact that, in previous works, estimate of the uncertain system matrices was used in the controller design. In our study, we removed the requirement for the estimate of the uncertain system matrices and yet still guarantee exponential tracking of a reference model.Conference Object Citation - Scopus: 3A Robust Adaptive Tracking Controller for an Aircraft With Uncertain Dynamical Terms(Elsevier Ltd., 2014) Tanyer, İlker; Tatlıcıoğlu, Enver; Zergeroğlu, ErkanThis work presents, the design and the corresponding analysis of a nonlinear controller for an aircraft system subject to uncertainties in the dynamics and additive state-dependent nonlinear disturbance-like terms. Specifically; dynamic inversion technique in conjunction with a robust integral of the signum of the error feedback and an adaptive term is utilized in the overall controller design. Lyapunov based stability analysis techniques are then utilized to prove global asymptotic convergence of the tracking error. © IFAC.Conference Object Citation - Scopus: 1A Robust Dynamic Inversion Technique for Asymptotic Tracking Control of an Aircraft(Institute of Electrical and Electronics Engineers Inc., 2013) Tanyer, İlker; Tatlıcıoğlu, Enver; Zergeroğlu, ErkanIn this paper, a tracking controller is developed for an aircraft model subject to uncertainties in the dynamics and additive state-dependent nonlinear disturbance-like terms. In the design of the controller, dynamic inversion technique is utilized in conjuction with a robust term. Only the output of aircraft dynamics is utilized in the controller design and acceleration measurements are not required. Lyapunov based stability analysis is used to prove global asymptotic tracking. © 2013 IEEE.
