Pursuit-Evasion on a Sphere and When It Can Be Considered Flat

Pursuit-Evasion on a Sphere and analogs to Apollonius Circle

Determining Follower Aircraft's Optimal Trajectory in Relation to a Dynamic Formation Ring

The specific objective of this paper is to develop a tool that calculates the optimal trajectory of the follower aircraft as it completes a formation rejoin, and then maintains the formation position, defined as a ring of points, until a fixed final …

Competitive Perimeter Defense of Conical Environments

We consider a perimeter defense problem in a planar conical environment in which a single vehicle, having a finite capture radius, aims to defend a concentric perimeter from mobile intruders. The intruders are arbitrarily released at the …

Optimal Strategies for the Game of Protecting a Plane in 3-D

A conflict between rational and autonomous agents is considered. The paper addresses a differential game of protecting a target in the 3-D space. This problem highlights the strong correlation between the highly dynamic scenario, the uncertainty on …

Power Management for Noise Aware Path Planning of Hybrid UAVs

Here we consider the problem of path planning for a hybrid fuel Unmanned Aerial Vehicle (UAV), equipped with both a battery and gasoline generator as two sources of energy. Routing the vehicle while considering this setup adds fuel constraints in …

An Optimal Engagement Zone Avoidance Scenario in 2-D

In this paper, an optimal control problem is considered where a target vehicle aims to reach a desired location in minimum time while avoiding a dynamic engagement zone. Using simple motion, four potential approaches are considered. First, the …

Continuous Monitoring of a Path-Constrained Moving Target by Multiple Unmanned Aerial Vehicles

In this work, a continuous monitoring scenario where multiple unmanned aerial vehicles are tasked to monitor a dynamic target moving along a path with unknown speed profile is addressed. Optimal trajectories based on the nominal trajectory of the …

Persistent Monitoring by Multiple Unmanned Aerial Vehicles Using Bernstein Polynomials

A framework for monitoring a target modeled as Dubins car using multiple UAVs is proposed. The UAVs are subject to minimum and maximum speed, maximum angular rate constraints, as well as inter-vehicle safety requirements and no-fly-zones. The problem …

Optimal Defense of High Value Airborne Assets

Optimal control theory and differential game theory is applied to the study of the defense of high value airborne assets, particularly in the case of a single threat such as an adversarial aircraft or missile. Rather than utilizing onboard defenses …

Optimal Evasion in an Active Target Defense Scenario

A three-agent scenario is considered in 3-D Cartesian space, where a Pursuer aims at intercepting an Evader while the Evader aims to out-maneuver the Pursuer. A Defender working in cooperation with the Evader aims at intercepting the Pursuer before …
