Numerical investigation of the hydrodynamic characteristics and interactions of an unmanned surface vehicle chasing a mother ship during recovery

open access: yesBrodogradnja
Unmanned surface vehicles (USVs) require efficient and reliable recovery at sea. However, the recovery process, involving USVs chasing a mother ship, is complex and risky due to wave-making and wake effects that impact USV stability and resistance. It is

Evolutionary design of a full-envelope full-authority flight control system for an unstable high-performance aircraft [PDF]

open access: yes, 2011
The use of an evolutionary algorithm in the framework of H1 control theory is being considered as a means for synthesizing controller gains that minimize a weighted combination of the infinite norm of the sensitivity function (for disturbance attenuation

Modelling of a captive unmanned aerial system teledetecting oil pollution on sea surface

open access: yes, 2012
Recent major oil-spills were tracked using observations with sufficient altitudes over the sea surface, to detect oil slick locations. For oil-spill responders, we propose a captive Unmanned Aerial System, UAS acting like a periscope over a ship or ...
