Nonlinear Model Predictive Coordinated Standoff Tracking of Moving Ground Vehicle [PDF]
AIAA Guidance, Navigation, and Control Conference, 2011 This paper proposes a nonlinear model-predictive control framework for coordinated standoff tracking by a pair of unmanned aerial vehicles. The benefit of this approach is to get optimal performance compared with using a decoupled controller structure: heading control for standoff-distance keeping and speed control for phase keeping.

Design of Standoff Cooperative Target-Tracking Guidance Laws for Autonomous Unmanned Aerial Vehicles [PDF]
Mathematical Problems in Engineering, 2021 This paper investigates two guidance laws of standoff cooperative tracking static and moving of multiple autonomous unmanned aerial vehicles for targets from the perspective of the control system design. In the scheme of the proposed guidance laws, one vehicle is chosen as leader and others as followers.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites
Journal of Polymer Science, EarlyView.In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Metasurface-Assisted Ultra-Wideband Radar for High-Sensitivity Non-Contact Respiratory Detection
IEEE AccessNon-contact respiration monitoring using impulse-radio ultra-wideband (IR-UWB) radar is attractive because of its low transmitted power, fine range resolution, and clutter-rejection capability; however, practical performance at meter-scale standoff is ...
