2024年12月23日 · Precise path following is essential for reliable multi-rotor unmanned aerial vehicle (MUAV) operation. Current control strategies suffer from control singularities due to a mismatch between the number of actuators and the degrees of freedom of the MUAV. This paper proposes a 2-manifold modeling approach for MUAV control systems.

In contrast, simulation results presented in Figs. 15 and 16 indicate that SSUKF is more sensitive to increasing noise level and it has resulted in unsatisfactory estimation and control of manipulator joint angles, which will lead to total loss of MUAV control.

Pg. 14 (fig. 2), 21-24, 80-110. Muav limestone of Tonto group. Restricted to mottled limestone facies. Includes minor amounts of platy, silty limestone and GIRVANELLA or algal limestones in marginal areas. Numerous excellent key beds which serve as time planes are developed in various parts of Muav formation.

2023年9月27日 · Towards this, a framework is developed to estimate microgravity performance measures such as 0 g -time, payload capacity, and 0 g -quality for a given MUAV. The proposed estimation framework requires only the data provided by the MUAV manufacturer to compute all the microgravity performance measures.

2022年3月1日 · This paper presents a new framework to identify the dynamic characteristics of a multirotor unmanned aerial vehicle (MUAV). In particular, the identification framework is applied for an arm stretchable morphing MUAV. This MUAV is capable of adjusting the arm length during flight to maximize performance as well as stability.

2020年5月1日 · This article presents a structural optimization method based on the approximate model and the NSGA-II to optimize the structure of a MUAV-based pan–tilt system, by which both properties of light mass and high first-order modal are eventually achieved.

Air Force has also conducted a series of flight tests to test the capability of manned aircraft and multiple unmanned aerial vehicles to cooperate with each other. Figure 1 is the air's projects...

We describe, interpret, and establish a stratotype for the Frenchman Mountain Dolostone (FMD), a new Cambrian stratigraphic unit that records key global geochemical and climate signals and is well...

2021年2月24日 · Our C-UAV system based on defense UAVs (dUAVs) which can autonomously and collaboratively act as a defense swarm. Malicious UAVs (mUAVs) can then be intercepted, captured and escorted out of the flight zone.

Our modified depositional model provides a more effective teaching tool for fundamentals and nuances of modern stratigraphic thinking, using the Tonto Group as a still-influential type location for understanding transgressive successions.
