Nonlinear optimal control for UAVs with tilting rotors

Gerasimos G. Rigatos, Masoud Abbaszadeh, Bilal Sari, Jorge Pomares

A distinctive feature of tilt-rotor UAVs is that they can be fully actuated, whereas in fixed-angle rotor UAVs (e.g. common-type quadrotors, octorotors, etc.), the associated…

Modified invasive weed optimization-based path exploration for mobile robot

Ipsit Kumar Dhal, Saroj Kumar, Dayal R. Parhi

This study aims to modify a nature-based numerical method named the invasive weed optimization (IWO) method for mobile robot path planning in various complex environments.

Study of jet tabs in 2D convergent–divergent nozzle for thrust vectoring in aerial vehicles

V.M. Jyothy, G. Jims John Wessley

In this study, 2D density-based SST K-turbulence model with compressibility effect is used to observe the flow separation and shock wave interactions of the flow. The wall static…
