Collision Avoidance in Cooperative Missions: Bézier Surfaces for Circumnavigating Uncertain Speed Profiles
Autor: Naira Hovakimyan, Syed Bilal Mehdi, Ronald Choe
Publikováno v: Journal of Guidance, Control, and Dynamics. 42:1779-1796
This paper presents a collision-prediction and avoidance algorithm for multivehicle cooperative missions. Using Bezier surfaces, the algorithm avoids time discretization of trajectories and is capa...

Piecewise Bézier Curves for Avoiding Collisions During Multivehicle Coordinated Missions
Autor: Syed Bilal Mehdi, Ronald Choe, Naira Hovakimyan
Publikováno v: Journal of Guidance, Control, and Dynamics. 40:1567-1578
This paper presents a Bezier-curve-based collision prediction and avoidance algorithm for multivehicle cooperative missions. The proposed algorithm runs on each vehicle independently from other veh...

Cooperative Trajectory Generation Using Pythagorean Hodograph Bézier Curves
Autor: Venanzio Cichella, Javier Puig-Navarro, Enric Xargay, Ronald Choe, Naira Hovakimyan
Publikováno v: Journal of Guidance, Control, and Dynamics. 39:1744-1763
This paper presents a cooperative trajectory-generation framework to efficiently compute a set of spatial trajectories for a team of cooperating vehicles: in particular, for unmanned aerial vehicles. The desired, feasible trajectories are generated u

Safe Coordinated Maneuvering of Teams of Multirotor Unmanned Aerial Vehicles: A Cooperative Control Framework for Multivehicle, Time-Critical Missions
Autor: Venanzio Cichella, Naira Hovakimyan, A. Pedro Aguiar, Isaac Kaminer, Vladimir Dobrokhodov, Syed Bilal Mehdi, Antonio M. Pascoal, Enric Xargay, Ronald Choe
Publikováno v: IEEE Control Systems. 36:59-82
Multirotor unmanned aerial vehicles (UAVs) have experienced a very fast-paced technological development over the past years. Flight control systems have evolved from simple stability augmentation systems, barely enabling an external pilot to remotely

${\mathcal L}_{1}$ Adaptive Control for a Class of Uncertain Nonaffine-in-Control Nonlinear Systems
Autor: Naira Hovakimyan, Enric Xargay, Ronald Choe
Publikováno v: IEEE Transactions on Automatic Control. 61:840-846
This technical note presents an ${\mathcal L}_{1}$ adaptive controller for a class of nonlinear uncertain systems, nonaffine in control. As compared to previous ${\mathcal L}_{1}$ architectures for nonlinear nonaffine-in-control systems, the solution

Cooperative Path Following of Multiple Multirotors Over Time-Varying Networks
Autor: A. Pedro Aguiar, Isaac Kaminer, Vladimir Dobrokhodov, Naira Hovakimyan, Enric Xargay, Ronald Choe, Venanzio Cichella, Antonio M. Pascoal
Publikováno v: IEEE Transactions on Automation Science and Engineering. 12:945-957
This paper addresses the problem of time-coordination of a team of cooperating multirotor unmanned aerial vehicles that exchange information over a supporting time-varying network. A distributed control law is developed to ensure that the vehicles me

Multi-leader coordination algorithm for networks with switching topology and quantized information
Autor: Naira Hovakimyan, Isaac Kaminer, Enric Xargay, Ronald Choe
Publikováno v: Automatica. 50:841-851
This paper analyzes the stability and convergence properties of a proportional-integral protocol for coordination of a network of agents with dynamic information flow and quantized information exchange. In the setup adopted, each agent is only requir
