A Computationally Tractable Path-Planning Method for Airborne Wind Energy Systems
Manuel C. R. M. Fernandes, Fernando A. C. C. Fontes
Airborne Wind Energy Systems (AWES) have emerged as a promising renewable energy technology that exploits stronger, more consistent high-altitude winds via tethered airborne device…
Geometric Look-Angle Shaping Strategy for Enclosed Inspection
Amit Shivam, Manuel C. R. M. Fernandes, Sergio Vinha +1
This paper introduces inspection through GLASS, a Geometric Look-Angle Shaping Strategy for enclosed regions using unmanned aerial vehicles. In doing so, the vehicles guidance comm…
Prescribed-Performance-Aware Hybrid-Gain-Based Robust Controller
Amit Shivam, Kiran Kumari, Fernando A. C. C. Fontes
This paper proposes a prescribed performance function aware hybrid gain finite time sliding mode control framework for a class of nonlinear systems subject to matched disturbances.…
Variable L0 Guidance Strategy: Enlarged Operational Envelope and Path-Following
Amit Shivam, Manuel C. R. M. Fernandes, Fernando A. C. C. Fontes +1
This paper presents a geometric and theoretical study of an exponentially varying look-ahead parameter for UAV path-following guidance. Conventional guidance laws with a fixed look…
Robust Control Design Using a Hybrid-Gain Finite-Time Sliding-Mode Controller
Amit Shivam, Kiran Kumari, Fernando A. C. C. Fontes
This paper proposes a hybrid-gain finite-time sliding-mode control (HG-FTSMC) strategy for a class of perturbed nonlinear systems. The controller combines a finite-time reaching la…
A Stabilizing NMPC Strategy for a Class of Nonholonomic Systems with Drift
Huu Thien Nguyen, Fernando A. C. C. Fontes, Ionela Prodan
In this paper, we present a stabilizing Nonlinear Model Predictive Control (NMPC) scheme tailored for a class of nonholonomic systems with drift, where the acceleration is laterall…
Automatic Circular Take-off and Landing of Tethered Motorized Aircraft
Sérgio Vinha, Gabriel M. Fernandes, Huu Thien Nguyen +2
We consider a motorized aircraft tethered to a central anchorage point in a configuration similar to a control line model airplane. For this system, we address the problem of autom…
Trajectory Optimization and NMPC Tracking for a Fixed Wing UAV in Deep Stall with Perch Landing
Huu Thien Nguyen, Ionela Prodan, Fernando A. C. C. Fontes
This paper presents a novel recovery technique for a fixed-wing UAV (Unmanned Aerial Vehicle) based on constrained optimization: i) we propose a trajectory generation for landing t…
